In an interview with Game Developer magazine, Keita Takahashi had this to say about the Revolution:
“I’m not really interested in it. I don’t think a controller should have that much influence on the enjoyment of games. I see what [Nintendo is] trying to do, but they’re putting such emphasis on the controller; ‘Whoa, this controller lets you do this!’ and I’m thinking - are you messing with us? So, there’s nothing I really want to do with it right now.”
Looks like Takahashi won't be developing for the Revolution.
