Well seems rather likely, mainly due to the lack of competition it'll have for awhile. I don't know if that is because of the weakness of other developers in that category or j ust because it is so strong but it has already been able to survive MAG and Bad Company 2 even with the latter putting up big sales. And this showed for the previous CoD games as well as Modern Warfare 1 and World at War both sold well despite big first party shooter releases.
Guess when we look down the road, it's really not til the next Call of Duty game comes out can something even be on the same level with it to start taking away sales. Until then, looks like the definite shooter for the system that will maintain high sales. I think it has a shot, but I also think as we get to the summer months, sales will start to slow especially as hardware sales start to slow.
