I think it ll be a mistake for MS release natal in 360, this generation in 2 years (maybe least) is gonaa be done. A natal with a new console (I already thought new xbox will be released before ps4 and wii2) will be very profitable.
MS----->Natal
Ninty--> HD
Sony-->?
However it is gonna be great but not as much as many people think. =P
