Looks like our old friend Jimmy Fallon will be demoing Microsoft's Project Natal on Late Night tonight, and this backstage pic from rehearsal is the first shot we've seen of the prototype hardware anywhere. Of course, Redmond's made it clear that the final product will look a lot different -- probably something more like the press pic -- so don't get crazy over this, but at least everyone's burning curiosity has been satiated. Now, Jimmy, if you could just hammer out a ship date, that'd be great.
