with 25+ million sales and counting, I do not think Activision is concerned.
Looking at it, MW2, Black Ops and MW3 have combined for 75 million sales and that is just amazing for a non nitendo games.
It bigger then any non-nitendo series.
Nonetheless if I was Activision I would release like a spin off game which would easily get like 15+ million sales anyways and then release a new proper advance game in 2013.
I think COD does not deserve all the hate, they are the same thing over and over but it works well and is a lot of fun. The FPS campaign makes all the current ones look like small potaoes and the multiplayer is better then all other games apart from BF3 but that is only for certain gamers.
I played BF3 and it was okay, the campaign was just sad in comparison to a COD game.
