I dunno man. Beyond one rumor I've heard everything is pretty much pointing too a next year release for the 720.
This year's E3 had to pretty indicative of what's coming. Look at the annoucments from first party stuff microsoft had this E3.
Halo 4 (out)
Forza Horizon (out)
Fable the Journey (out)
Nike+ kinect (out)
Dance central 3 (out)
Usually games are shown at E3 even though they won't hit the fall of the next year. Microsoft didn't show any of that. The three other spotlight first party titles they showed (Ascend, Matter, Lococycle) are all xbla and are set for a spring release.
Development news on ryse has gone silent with the expections of it losing kinect and rumored to have gone next gen.
So far the only real big content microsoft has for next year are gears of war judgement and Halo 4: spartan ops season 2 (if that counts).
Most of microsoft's first party development are confrimed to be working on next genration content.
Activsion has implied that a new console is launching next year.

They want the next generation of the surface, the surface phone, the next xbox, and the windows blue updates to hit pretty close to each other.
I wonder if Sony will add something more user friendly if they decide to revamp home for its next console. It would be cool to see sackboy and his world become the basis for home.
