Well anything could happen. We are talking about treyarch the masters of getting into our heads. They are making us go crazy by making up theories. Thats whats been happening ever since the beginning of zombies as we know it. Look at ascensoin from black ops 1. People were going crazy trying to go farther past the 90 second death machines but you couldn't. People kept saying that you could get into a big battle with samantha but nothing. Proof that treyarch just trolls trolls and trolls.
Overall i think they are going to go all out on the final dlc.
