The Xbox Xenon?
Xbox-scene.com has what is purportedly a screenshot from the Xbox 2 Developers Kit (which software publishers use to create games) listing the name of the console as the "Xenon", a suspected codename which has been floating around since last year. Probably not what they'll end up naming it, but there's lots of speculation that Microsoft would rather call it the Xbox Next or the Xbox Xenon or whatever rather than the Xbox 2 since they're worried that calling it that willl somehow make it seem like it's less powerful than the PlayStation 3.
