Grand Theft Auto V is in playable form, and at least one reporter is getting his hands on it today.
Game Informer editor-in-chief Andy McNamara wrote on Twitter today that he's at Rockstar, checking the next Grand Theft Auto game out for the magazine's December cover story.
This means we could see a release date very soon. Game Informer typically reveals its covers (along with details on the game it is showing off) during the first week of the month before the one on the issue. So we should hear more about Grand Theft Auto V in early November.
