I think it will sale with the three games that are made for it. Like many others have said this will be like DDR pads and the Guitar while they are cool and fun to pay it doesn't go very far (as far as selling systems). The PS3 and the 360 don't need this so delevopers are not going to put millions behind a game for this on the 360/PS3. Nintendo has nothing but motion controls so you will always see much more elaborate games using it on the Wii, plus you have the Nintendo brand name and all this recent news in the media vs IN2games.
