Why wouldn't Microsoft want to release "Xbox 720" one year before the PS4?

Yeah but i think they will see how Natal will be first.

This sounds about right. If Natal is big, it could push a new system back 2-3 years. Of course, the 360 is always evolving and getting better, so it's not like it's the same 360 as at launch either.
