the only reason why the balance board is such a success is because of its mass audience appeal. Wii fit appeals to any one over the age of 15 or what not who might be interested in their physical apearance or ability. the younger kids would still be drawn to it but after playing it I cant see how the younger kids would be drawn to this game for the long term.
Ms needs to release a game along side the motion device that has the appeal of their mass audience, would we say they are fps fans? so it would make sence to release something along side that genre other wise with the recent hype about wii fit and the wiis motion control in general the 360 remote may get swollowed up in nintendo hype.
This casual motion controle oriented audience is going to be a hard one to crack because they will need to do one up if not two up on nintendo to really attract the audience that will push the success of the device
If at first you don't succeed, you fail
