When I come to think of it, for Microsoft and Sony. the Wii tested the market pretty well and when they saw the amount of moola that could be made from motion sensing, they took the opportunity. Nintendo, on the other hand, has always had its heart in the family/ multi-player arena - just look at the Gamecube (mind a few of the more hardcore games). Nintendo also tried to introduce something innovative to the market, which is pretty respectful considering the abominable lack of innovation these days, and it just happened to appeal more to the casual market. When you compare Nintendo to those other two capitalistic giants, you have to wonder the different reasons for them introducing their respective motion sensing abilities.
