Don Mattrick, senior VP of Microsoft's interactive entertainment business:
"I think we've got the best thumb-based controller ever created," Mattrick told Edge. "We're not going to take anything away. There will be controller-based games. What we're really doing is adding to our platform; when I think about Natal, I think of it like a Guitar Hero controller-it fits the experience better. There will still be games that use the controller, games that use only Natal, and games that use a combination."
