Next Generation Motion Controller For All Consoles and PC?

Companies Motus and Gyration are rumored to be working on a next generation motion controller similar to the Nintendo's Wii controller. It's also rumored to work with PS3, Wii, XBOX 360 and PC. Motus currently has a controller called "Darwin" (pictured), but they deny working with Microsoft on a new controller rumored to be called "Newton". Will the future (or the next big thing) of gaming be all motion sensitive?
