Well I guess everyone ought to go take a course on how to be a Mime. Because that's what Natal seems to be..you interact with stuff that's not there, except you can make noises.
That's cool and all, but the Burnout thing is dumb. The reason I say this? The petal sounds cool..unless you've ever played rock band or GHWT and have had to use the drums. My foot hurts enough using the petal..having to suspend it with nothing to support it? I'll pass.
This has potential. I won't deny that. But only if MS uses the technology right.
