Gametrailers has just put up a promo for their next episode of GTTV, which airs this Thursday, stating that it will include a world exclusive reveal of the next big Sony game.

Geoff has also teased that this is a surprise announcement, so what could it be. Perhaps it is a sequel to LittleBigPlanet, Sony did after all just acquire Media Molecule, or maybe it's the long awaited Starhawk. In fact it could even be a franchise that has yet to grace the PS3, Syphon Filter anyone? Whatever it is, we're sure it'll be great.

Let the speculation begin.
