Bungie wants to make money, and they don't want to be restricted. This game IS FOR XBOX. But it is also for the Playstation. Because the next Xbox hasn't been revealed, Bungie can't come out and say it is for the next Xbox as well. Be patient. As for why this game isn't JUST for the Xbox. Bungie is free to sell their game to whomever they like. Does that make this game bad in anyway? No. Are you that of an entitled little brat that you ONLY want it for YOUR console of choice? If the answer to that question is 'yes', please go away.
