Which one do you think will sell the most? Will it be the 360 version with 43,9m userbase or the PS3 version with 38,9m userbase or the wii version with 74,6m userbase?
Usually on CoD games, the 360 version has been the biggest seller, but there has been many points on why other versions have done worse. Now the game releases at the same time on all three platforms and as a multiplatform game, the advertisement is not an excuse.
