I have seen so many people saying it can't be a MP gun because "No one would have the model etc. for it", has anyone heard of title updates? Specifically the ones that are released with EVERY DLC?? They can add the gun to everyone's xbox through the title update...... But leave it locked for those who don't have the DLC.
For example, a man who is lvl 55 uses the AN-94, he dies with it and then a lvl 12 proceeds to pick up this AN-94. No problems, the gun is in the game, but it is just locked for the lvl 12.
Since IW had 17 multiplayer maps with a lot of spec op missions for MW3 I think they try to get the funds to implement more stuff in the coming DLCs, why else would they want to cash in on all 4 map pack at once letting people pre-pay the DLCs.
Implementing a strong gun into MP would also be an incentive to buy and the more map-packs people buy the more funds can be spent on later map packs or DLCs.
