Don't worry about the fuzzy screenshot there. It's just a still from a live Twitch stream of Titanfall on the Xbox 360 being played right now.
EliteXbox360Gaming promises HD video footage will be going up on their channel soon. Until then, they're streaming live.
Commenter YepYep also pointed out this archive of the game being played on the Xbox 360 earlier, which might be more exciting than waiting on menus.
