First things first: I'm saying this is a possibility, it may or may not actually happen. On the Nintendo channel there is a developer's interview with Ken Levine, Irrational Games' Creative director. During the interview, he talks about the new controller design and a little about Bioshock Infinite. There was nothing said about the release of the game for Nintendo but there was footage of the game in the video. What makes me believe this may be a possibility is that the Nintendo Channel never shows game footage of games that aren't for Nintendo systems. This may be an exception or this could actually be hinting at a release. We won't actually know until a release date or a Wii U release is announced.
