Japan's "locked down," but he's taken Nintendo's global presence and damn-near torpedoed it into toward irrelevancy.
Frankly, I don't know why people focus so much on the two years of loss Iwata's responsible for (although, when you consider that Nintendo has been profitable all this time, those two years of loss are pretty significant.). That's not the most damning thing. A decision to fire Iwata is not going to come from two years loss alone. Rather, it will be the board looking at that loss, and at how Iwata has set up the company to perform going into the future.
And, honestly, that's where the picture gets WORSE for Iwata (and why I think he needs to go ASAP). He hasn't just lost Nintendo short-term money, I'm afraid he's positioned Nintendo in an industry gray area where they'll never again be a competitive, dominant force outside of their own increasingly shrinking bubble.
Iwata has just run Nintendo so conservatively. Too conservatively. Nintendo's missed the opportunity to get in on the ground floor with so many dominant technologies and trends (online and robust content ecosystems, HD development, western gaming culture, etc.). Iwata neutered NoA and consolidated Nintendo's development presence to Japan JUST as the gaming nexus was shifting to the West, and now Nintendo has next to ZERO clout with the western development houses that make the most in-demand games, resulting in 3rd party support being the WORST it has ever been for a Nintendo console. This is made worse by the fact that Nintendo has few-to-no answers for these types of in-demand western gaming experiences in its own first party lineup-- and this is thanks to Iwata's completely insular, Japan-centric thinking. People attempt to gloss over Iwata's failures by pointing out their progressive policies with indie developers, but you can't count on fucking indie games to save a platform, and in just a few short weeks both Sony and MS have amended their policies to match and completely stolen their thunder on that front, too.
So, if I'm an investor, I'm not focusing on the two years of loss. I'm focusing on the future, and wondering just where the hell Nintendo as a company can go under a man as conservative, insular, and lacking of vision as Iwata after the success of the Wii/DS.
The answer, as we're discovering, is nowhere but down.
This is a tired one-sided narrative - summing up: "Nintendo lost the West and is d00med here" and "Iwata is insular and conservative" - try something that isn't repeating stereotypical memes based on your unfounded assumptions of Nintendo as a company.
The first thing people need to understand about Nintendo is that they are a design company, like Apple. They will have tremendous hits and flops over time, but net-net, they are creating shareholder value - which is why the company has $14 billion in cash and short-term holdings making it the most valuable gaming company in the world.
Running a design company isn't about jumping on trends, it's about fostering a creative culture where people are free to work and create, and then jumping on key products as they are built and figuring out how to get people to buy them. That's a tremendous job. That is why Steve Jobs was respected the way he was. This is why Satoru Iwata is highly respected within Nintendo. These guys are going to make mistakes and they are going to do things that puzzle people (Jobs was famous for closed ecosystems, when everyone else was going open), but their internal teams love them, and they perform and work for him because they admire/respect him - and there is a cult of personality around them. You can't just bring in a mercenary fly-by-night executive looking to cash-in to run these companies. The talent would just get up and leave.
That said, Nintendo made a lot of wise choices in the past five years: they locked up Japan, which they feel is their cash cow market now largely abandoned by Sony and with Microsoft non-existent.
They also went on a hiring binge and got talent that was being laid off by other companies, and setup partnerships and joint-development opportunities with companies like Platinum and Mistwalker and Namco Bandai and Tecmo Koei - completely changing the way the majority of the game development community in Japan saw them. This took incredible time and effort frankly. Other than that, Nintendo has expanded Monolithsoft, Retro, and fostered relationships with a dozen smaller studios in Kyoto that are offshoots of employees from Konami, Square, etc.
They've also had to build out an entire OS team and built a social network through a partnership which they are managing internally. Nintendo also had to hire, over the past few years, tons of people in network engineering to bulk up on their core software abilities - unlike Microsoft which had people ready to go on that front. They are still lacking on this front but it's come a very long way and will improve - Sony is evidence of that. Even the Xbox has changed dramatically over the years.
More importantly: scaling up creative staff from say 1000 people to 3000 or more, for a company with such a unique workshop-like culture as Nintendo is really hard. Nintendo has the toughest hiring standards in the industry and have a very strong internal culture, and they are very careful about not ruining that - unlike Silicon Valley ponzi schemes that are trying to get bought in a few years and will hire anyone with a Stanford degree just to appease venture capitalists. Nintendo has had to exert tremendous effort to ensure they hire in a sustainable way where people work together and the culture thrives.
With what abilities they had and opportunities they saw I think they made the right choices.
In your world, they would have abandoned a few of the ideas above, and gone to the West where there were two camps: one were non-gaming executives running gaming companies fighting over the same pool of 1000-1200 developers, inflating salaries out of control, and desperate to try and release another shoot-bang game on HD consoles. Another group of people were proclaiming the end of traditional games as Zynga was going public and venture capitalists were dumping millions into Facebook games.
The latter: almost all of these companies failed miserably. Zynga is effectively on life support. There are a few small shops making tremendous money on these platforms, but it's a huge mess. The former? The jury is still out who will survive in the next five or ten years as we move towards real-world games with augmented reality and other types of gaming platforms like the Oculus Rift. Needless to say, few companies outside Activision made money in the last gen, and my bet is, EA might fold in another seven or ten years especially if they don't get to hold onto their exclusive sports licenses. I'll go out on a limb here: I believe EA is going to be nothing but a foot note in the pages of history. Nintendo is 120+ years old. They've seen dozens of EAs come and go over time.
So then, what should Nintendo have done in the West? Throw millions into California-based companies for no reason? Buy up studios only for the talent to leave? Money hat a bunch of games from developers that had no interest in making Wii games? I keep hearing all this talk about "Nintendo and West" - but there aren't a lot of compelling things Nintendo could have done. Building studios takes years, and Nintendo isn't just going to throw millions for another nightmare like Retro to occur which consumed incredible time from NCL and EAD.
As for your tirade about Iwata neutering NoA. NoA has been dead for years. That's the truth. Treehouse is the last good thing about it and that's because Nintendo's core localization team has been together FOREVER and all their kids go to school together - they are incredibly tight and will never leave unless something drastic happens. The rest of NoA? The Wii was such a novel product that many people coasted through, even though they had the ability to really get deep and do some impressive things with their fan community. That's a failure of Reggie and other execs, not Iwata who basically gave them the freedom to do what they wanted and even made a bunch of games like Xenoblade available for them to localize.
Part of the problem is that NoA never got great leadership after two rounds of poaching by Microsoft (once before the Xbox launched, another time right before the Kinect launched and Microsoft started doubling or tripling salaries to bring in Nintendo's marketing people), so this has been troublesome as Iwata does not have a trusted counterpart at NoA with a blood commitment to the company that Yamauchi did in the form of Minoru Arakawa. I honestly think this is why Iwata named himself CEO of NoA was because he wanted to play a more direct role in building executive capacity and ensuring that NoA was in position to succeed. He really needs to move to the US because NoA is playing games of musical chairs. The biggest idea Reggie has proposed has been TVii, and NCL let them do that - Reggie could have proposed any number of things frankly - but this is the best that came to his mind.
The human resource issue in the US partially exists because Nintendo has a unique way of going about hiring people. It doesn't want to hire mercenaries like Peter Moore who will sell their soul for a few bucks and jump company to company (some would argue Moore killed the Dreamcast just to curry favor with Microsoft and he himself said that Microsoft helped arrange his transfer to EA because they saw an opportunity to corner both Nintendo and Sony). Nintendo hires people who are passionate about their products, and are motivated by things beyond money - much like Howard Lincoln and Peter Main were during their tenure at Nintendo. Just consider this: Iwata gets paid $1.2 million bucks a year - Bobby Kotick who doesn't even play games - made over 50x that in a single year.
The other thing I'd like to remind people, is that America isn't the only market important to NCL. Europe is frankly, just as big and just as important to Nintendo, if not more important given some of the shared gaming tastes in Europe. Nintendo spent TONS of money on marketing in Europe going from a has-been to holding the console crown when the Wii came out. NoE does a ton of work behind the scenes that people are not aware of to get Nintendo from constant third place finishes to where they ended up in the Wii days. Do you guys think this just happened magically? We don't hear a lot about how engaged NCL got into Europe - but there are a lot of NCL people that flew back and forth between Japan and Europe during the Wii days to give it the kind of coverage it now has - and this consumed Iwata's time.
This is all my opinion frankly, and I say this more to try and counter this ridiculous and IMHO ethnocentric inertia of "Iwata is a fool, doesn't get the West, and is keeping NoA weak cause Japanese companies are pride LOL lol lol!!111" - but I hope what I say will resonate with some of you - running Nintendo isn't a joke - Iwata is a great executive who is finally growing into his role. Yamauchi made LOTS of mistakes early on and Nintendo lost a ton of money with his ill-advised ventures. But that's the beauty of Nintendo - they really want to grow their executives and give them leeway to make mistakes - Iwata will learn - and when he figures out NoA - I am sure Nintendo will have an amazing core team in both Japan and America.
tl;dr --- There really isn't anyone better than Iwata who has the respect within Nintendo's creative teams, support from shareholders, and an overall desire to see it move forward, that could come in and do the things that an extremely off-beat culture like Nintendo is now doing for the future.
