Whether Zombies is copyrighted or not, it still doesn't give Sledgehammer Games the right to copy a gamemode and do a simply slight name change and 2 or 3 new/changed features, and claim it's new.

As much as I liked zombies, we got it in three different games, and as said in another blog comment, I believe that the community got fed up with three years of zombies, so they want something new. Giving us the same mode over and over again will certainly not give a positive result.
