Sly Cooper Thieves In Time Coming To PlayStation Vita, Too

Sony's PlayStation 3 exclusive Sly Cooper: Thieves In Time will be coming to the PlayStation Vita this fall, alongside the PS3 release. The game will feature cross-platform play, letting owners of both versions pick up and play wherever they've left off, on whichever platform they happen to be playing on (Vita or PS3).

The news comes from last night's episode of GTTV with Geoff Keighly, where developer Sanzaru Games made the announcement. We've the got debut trailer of the Vita version below.

But seriously, why is Sony revealing all of these games before E3? What do they have up their sleeves?
