Zombie or no zombie?Edit
Thats the question!
The zombie trail has been found by treyarch and used and I know that IW announced that they aren't going to pursue the dead but think about it we all love zombies and imagine new features only availible in MW3. Juggernaut zombies. Undead ops. But they would have to think of a whole new plan for it. The should set it in the land of Bahraaaaaaaaaaaaaaaaaaaains... um, atually no they shouldn't
