I didn't watch the MS conference but was just browsing some videos and from what I saw the only titles that interested me could come to WiiU. The Max and the Magic Marker sequel might be good and Capybara's Below is my kind of game. I'll be sure to check Below whenever it releases on iOS, PC or WiiU.
FYI Capybara talked earlier today of Nitendo's big indie push:
