En 1er lieu, un profile Linkedin d'un employé de Treyarch, indiquant l'existence d'une version WiiU de Call of Duty Black Ops 2

"We really want to target and challenge the gamers with ZombiU because this game is very hard. So for example when you finish the game you will unlock a new mode called Survival Mode. You will have to finish the game with only one life and only one character. We know there are a lot of gamers expecting a lot with the Wii U, so that's why we want to deliver this experience and dedicate it to the gamers." - Ubisoft Monpellier's international product manager Nicolai Bouchai

Trad pour les non anglophone: Ubisoft n'oubliera pas les amateurs de difficulté extrême et proposera, une fois le mode solo fini, un mode "survivor" ou il faudra finir le jeu avec 1 seul et unique personnage
