Wonder how important it is for Microsoft to have the host of the Late Night show squealing "THIS IS THE FUTURE OF GAMING"? Or, on a more practical level, how important it is to be showing on TV that the whole thing actually works?
Oh, and the Devo jumpsuits? Probably something to do with the lighting, as it's likely the prototype camera was having a little trouble making out the player under full-blown studio lighting. That's my guess, anyway.
Shame we didn't get even one "BAM", though...
