I think God of War is number one because of the pre-orders here in America (I dont think its that popular in other places). This game already passed 1 million pre-orders and before the game comes out I wouldnt be surprised if they passed 2 million pre-orders. The game comes out in 4 days and im guessing first month sales to be 1.5 million in the US and overall in all the country's to be somewhere around 4-6 million.
