Keep it for when some ps4 exclusives come out. Try bloodborne for now and get uncharted later. I personally love the ratchet and clank games, so i have to namedrop that. That robot dinosaurs game by guerilla looks interesting too. Finally remember that there might be a sequel to the last of us coming, that should be enough incentive on it's own. I'm a playstation player since ps1, but wouldn't complain about getting a xbox at all. Enjoy the best of both.
