Retro says Wii U is “a powerhouse”, new game has been in the works for a few months

I think it could be Star Fox. I also don't think whatever it is, you'll see it for a while as it's almost certainly not coming out until 2016 most likely.

I wouldn't be shocked if its a launch/early gen title for Nintendo's next portable system rather than a Wii U game.
