I thought 360 was funny
I thought 360 was funny, since if you think of it as degrees of a circle, they'd be right back where they started.
Of course now that they've already used Xbox 360, it's not like they could use Xbox 3, and expect it not to cause a lot of confusion. So MS has kind of backed themselves into a bit of a corner, unless they want to name the Xbox kind of like Sony did with the PlayStation Vita. I'd vote for Albatross myself, but maybe only as an internal codename.
