Xbox Motion Sensing Controllers?? (Rumor)

Team Xbox has just brought to public attention the fact that Microsoft has been experimenting with motion sensing technology for the past two years. Kind of obvious really. I mean with a bank roll that deep for the Xbox division alone you would think there would be plenty of R&D in every department but especially this area of technology after Sony and Nintendo have implemented it into their controllers. I think Team Xbox is saying that these controllers won't appear in the Xbox 360's lifespan but rather the next generation of the Xbox. Hopefully, that gives them enough time to make it a lot better than Sixaxis, which was slapped together in order to take some of the medias attention away from the Wii and its motion controls when it was announced.
