Mystery "big" game coming to the Vita - Sony

Sony's hero of the hour, Shahid Ahmad, has set tongues wagging on Twitter that an amazing game is coming the way of the Vita. Hard to divine anything from his words. Hopefully, "hooked" doesn't mean another fishing game. But we'll see in due course just how big or amazing it is, and if its one of his indie conquests that are keeping the Vita running or he's talking about a major series from the wider Sonyverse.

Minecraft would be the obvious killer game, but what else could it be?

UPDATE: Shahid has confirmed that it is NOT an indie game, but he has no clue as to when it will be announced. Since we're already pretty sure Gran Turismo is on the way and has kind of been trailed, it should be something else shiny, new and  BIG.
