What do you see as the gaming potential for this beyond what was shown at E3. Someone mentioned it would be cool for a snowboarding or skatboarding game, using the pressure sensitive board to lean into turns, jump, etc.
I wonder if it would be nice for a track & field game where you could run on the board.
It could be used as bongos for a DK bongo game.
It could be used as a platform for a fighting game where you use the Wii Remote and Nunchuck to punch ala Wii Boxing (but with better tracking) and you lift your leg off the Balance Board to kick.
More ideas?
