I expect this to appear at the MS E3 performance, live gameplay... would not surprise me.
As for people saying why show this before E3... you know releasing it just before means you get press before tons of PR for lots of games come out, it's not a bad idea...especially if you are at E3 showing the game off (if they do that).
