Zombie mode is Treyarch things. It wont be in MW3..least it better not be.And yes, Zombie mode has over taken normal multiplayer online.
I wouldnt be surprised if they dont try a zombie mode of their own..maybe not zombie mode..but...idk...but something to hold peoples attention. Personally I dont know what they can do to keep my attention anymore. MW2 burned me and a lot of my friends. Black ops was a fun, playable game...and sadly the most we do in that is play zombie mode..so..what can IW do to get players that were angered by MW2? I dontknow.
