Chris, don't get upset. I'm not saying Wii U sold well, I'm not saying Wii U games sold well, I'm no saying Wii U will sell well, I'm not saying third parties will jump on board (they never did, indeed), etc. I just want to understand better the overall situation, because if you are really so clear-cut with the platform, you must have some reasons, but I don't also excluse over-reactions. Wii U games had very low sell-throughs? True, but low sell-through are quite typical in general, as Spiegel posts showed. To me, it seems that people tend to forget how previous platforms releases went. Does Wii U have problems? YES. Was Wii U one of the worst launch ever? Hardware-wise no, of course; software-wise, so and so, in the sense that it could have done well, and it did way worser than Wii. But it did also much better than Vita, PS3, let's say.
To me the real takeaway from the Wii U's launch is that it will be extremely hard from them to win the generation before all the competitors are on the field.
With the Vita, simply looking at the 3DS's line-up and the Vita's line-up a month or two before the Vita's launch would easily tell you that the 3DS would be in first place.
For the Wii U, barring a major surprise, it is unlikely that the system will solidly get out of the sales doldrums prior to at least August/September when Nintendo could feasibly release a notable unannounced Wii U game, and even then this isn't assured to skyrocket sales despite being pretty close to the PS4's rumored launch.
So to me, the longer term strategy and challenges for each company, assuming they want to sell well, would be as follows:
Sony:
Sony is probably in the most precarious situation simply by virtue that they don't have a relevant first party in Japan. The only team at SCEJ that has proven they can consistently release hit games is Polyphony, who takes forever and has sales that are good but extremely Euro-centric. This means that Sony will once again have to rely on third parties and/or first party publishing deals with independent developers. However, as of our last update, the difference between the Xbox 360 and PS3 in Japan represents less than 10% of Sony's worldwide PS3 shipments. When refocusing the company, especially after the failure of the Vita, there is an argument that Sony could decide that Japan simply isn't worth it and spend their resources on fighting Microsoft in the West instead where they are notably stronger by volume. Their actions so far though haven't suggested this is a notably likely outcome.
So, assuming they actually care about the region, this means that Sony's best bet would be the following two part strategy. The first part would be to line up a set of moderately notable titles (for Japan) and spread them across the first six months of the system. Whether this consists of notably upgraded PS3 ports, first party publishing deals, or niche titles that can deal with a smaller number of sales is up to them. The goal here is simply to make sure they have a steady line-up of games where consumers can say, "Hey, if I get this, at least I have something to play now." The second, notably more crucial part of this strategy would be to present multiple huge titles for Fall/Winter 2014 where they can sit there and say "This is why you absolutely, positively want a PlayStation 4 by Fall/Winter 2014." By offering something to do in the immediate term and a highly compelling reason to own the system by a year or so into the system, they can steadily win people over in the lead up to those games.
Of course, given the current Japanese climate, along with Sony being able to provide very little of this software on their own, this is not an easy task.
Nintendo:
Nintendo's main focus on the other hand would be to say "Hey, who cares what is coming out in Fall/Winter 2014 for the PlayStation 4, we have all the biggest hits RIGHT NOW!" Or, in other words, they want to show up to August/September 2013 - June 2014 with an incredibly strong line-up of titles that convinced Japanese consumers that this is the way to go, because hey, who wants to wait when the winner is already here? Releasing 3D Mario U, Mario Kart 8, Smash Bros 4, and Monolith's new game for the niche audience in that window would be a very strong showing, especially if they wrangle a few third party exclusives and at least a fairly healthy porting rate (~50%) from the PS3.
Of course, given the current Japanese climate, along with that being a notably large amount of high profile output for Nintendo in a relatively short window, this is also not an easy task.
If both of them execute, we could see a potentially interesting console race on our hands. If one of them executes and the other doesn't, that leaves a strong possibility of a notable victory. If neither of them execute, the 3DS will likely drive a bus over their hardware sales and pick up all the developers who were thinking of making Japanese focused titles for the systems, helping to kill off a notable portion of what remains of the Japanese console audience.
While they have until E3-TGS 2013 to present their line-ups for the future, we may at least get some insight into them in the near future. There will presumably be at least one Nintendo Direct by the end of February, and both press and GAF sources are favoring a PS4 reveal for February as well. If we start to see healthy line-ups for the future out of both of them, this is a good sign. If Nintendo focuses on their already announced Spring games and Sony's Japanese support consists of Dead Rising 3 and Thi4f, then both of them will likely get exactly the sales they deserve.
