Okay, so I messed up and thought that Batman was coming in September.
Its coming in June. So now I see why the situation is looking so bleak for Microsoft in the US.
Sony doesn't give a damn about November or December. They are going to run up a strong lead before Halo drops and they are going to make a profit doing so. They still have the advantage going into the holidays... with a lead and the opportunity for a price cut...whenever they feel like it.
