*sigh*, GTA will probably add more realism , like gas, cops still chase you after mission is done, and make the world bigger. Halo 3, unless some miracle happens it will be exactly like halo 2, a new feature here and there, maybe 2 new weopons, and like gryph said earlier, better graphics. But im pretty sure bungee will get it's arse handed to them if GTA Next gets released on the same day HALO 3 does. But enough said, Im gonna start collecting money for a, PS3
