Certainly doesn't affect the future of the franchise.

This isn't unexpected, as it is an Xbox 360/PC exclusive, and the only two games on the Xbox 360 in the top ten are Modern Warfare 2 and Red Dead Redemption, two games that are huge. Most of the other games are Wii and DS, two platforms that significantly outsell the 360, and the only PS3 game is God of War III, another huge franchise.

I don't think this is surprising at all, given the platform availability of the game.
