The sequel to Beyond Good & Evil has been off and on in development under Ubisoft for a long time. Fans of the cult-classic have been waiting eagerly for even the tiniest bit of news ever since its announcement years back, and it was even incorrectly thought that perhaps Beyond Good & Evil 2 would be at E3 2013. With the wait having been so long, Ubisoft has confirmed that the game is now in development for next generation platforms. Unfortunately, based on a recent interview with creator of Beyond Good & Evil Michel Ancel, it looks like next generation won't be including Wii U. Ancel says that, though it would be "possible," it would be "painful" to bring Beyond Good & Evil 2 to current platforms:

"I think [on current platforms] Beyond Good & Evil 2 was possible, but it'd be painful. It's always possible to do anything on any kind of console, but sometimes you need to spend your energy not on the optimizations or things like that. Now that we have the [new] consoles around the corner we're working on them. We're trying to see how we can get the power out of those consoles because there are still things we need to understand on those consoles, but yes, Beyond Good & Evil is a project I always have in mind and I hope good things will come for this project very soon" -- Michel Ancel

Based on the way he mentions Beyond Good & Evil 2's prospective platforms as being "around the corner" and Wii U, whether or not you see it as next-gen, being a "current platform," it makes sense to assume the long-awaited sequel will be skipping out on Nintendo's platform.
