cod 4 goty edition released for x360, how much will sells go up this week

[PS360ForTheWin]

I dont really think this will have much impact on 360 sales, its more likely to boost COD4 sales, it could be the key to making COD4 the most popular game on live, putting it ahead of halo 3, its a great game, but this is just a version with extra maps, its hardly a system seller.
