Twas the day before Christmas, and all through the house, not a creature was stirring... except for Rockstar's marketing department. This morning the developer posted several screenshots on the company's site for Grand Theft Auto 5 to elicit speculation. There's a swimming with sharks shot, along with a dog in the passenger seat of a car. Drive-by pooches confirmed?! There's also a mini submarine picture, as well as a shot featuring a commercial jet, a fighter jet and a blimp. No word yet if these are actual player-controlled vehicles for use in the game, but feel free to dream about that tonight, along with sugar plums dancing.
