6. Xbox 720 / Next Xbox
The next Xbox is currently in development, and that is an open secret.
However, Microsoft is unlikely to announce it this year as it would go against their announcement of the new Xbox 360 subscription and dampen everyone's excitement for Halo 4—arguably their biggest title this year.
Microsoft will want the Xbox 360 to last for as long as they can, and they'll do so by playing up enthusiasm for Halo 4 and videogames exclusive to the Xbox Kinect. Announcing a new console would make the Kinect seem obsolete and it'd dissuade anyone from wanting to pick up a new Xbox 360 in the meantime.
