It was a little sad seeing how many people at GDC had completely written off the Wii U
I mean, I get that GDC has historically been a PC-centric conference and more recently because of the California/LA/entertainment connections, Sony has really dropping a lot of money on the attendees and cozying up with the development community
but outside of the Criterion guys I met (one of the technical directors had a Super Mario t-shirt on so you can guess how they feel about Nintendo more generally), and your odd developer out (usually someone who grew up playing Nintendo games and really wanted to make games for Nintendo consoles so they put themselves in a position to do so), it wasn't even a factor - people had written off the 3DS as a dead console too (at least impossible for them to ever make a profit on)
the people running the Nintendo licensing booth didn't help matters any - I spoke to a few of the people there about Q&A, bug-fix support, etc and most of them were sales guys from Redmond that knew very little about the technical aspects that would be relevant to a developer, and few of them had any real understanding of what would get an existing indie to port their game to the console - kind of proves my statements about NoA all along - the guys are totally out of touch and NCL can't move their developer-relations on-shore fast enough to pick up the slack
again, not saying this is necessarily a bad thing, GDC has never been a Nintendo-friendly place, the PC development community has kind of existed parallel to Nintendo, but it IS an entire stream of games that Nintendo will probably never get now nor are they even on the radar of (currently) - so it just means Nintendo has to work all that much harder because capturing these devs starts before or right at the beginning of a cycle - and Sony is trying to pull a 360 right now, doing everything it can to get people to commit to the PS family of products right at the start of the cycle
Nintendo has been doing the same thing Sony has been doing, but in Japan, and getting more exclusive content for the next 24 months (whereas Sony is mostly going to get games that will be cross-ported to PC) - so we will hear more about that at E3 - but if you are a Nintendo developer in the US right now - it can be a bit lonely going to some of these development conferences (Nintendo should organize a NDC to boost morale a bit IMHO)
In case you guys are wondering though, the last time a Nintendo game got any real recognition at GDC was Metroid Prime, and IMHO that was only because you had a bunch of ex-PC devs at Retro who were well known in the industry as contributing to Quake mods - Mario Galaxy, its music, etc was barely recognized - based on my conversations over the years, I can't even think of a lot of PC devs that played the game.
I believe Wii Sports got some recognition for its innovation, but that's about it. In one of the sessions, Atari was recognized as "building the modern console gaming industry" - Nintendo was basically not even mentioned. I don't think it's necessarily bias, it's just a reflection about how a lot of these developers think about the world (especially on the West coast).
