The major rumor of the day is that Ubisoft is working on a AAA game for the Wii U that could possibly be an MMO. On Ubisoft’s official Facebook page they listed openings for a Network Programmer and Senior Engine Programmer vacancy to create a ”AAA title” for the Wii U. In addition, a Tools programmer for a AAA MMO was also listed; however this may not be connected to the Wii U project but they might be considering all three job openings were posted on the same day.
Earlier this year at E3, Ubisoft made it abundantly clear they were supporting the Wii U with games like Assassin’s Creed, Ghost Recon and Rabbids being made for the Wii U. They also announced at E3 they would be creating two new IPs, one being revealed as Killer Freaks From Outer Space (not much is known about the game) and the other new IP has yet to be announced.
In other words, more than likely that unannounced new IP is what Ubisoft is hiring for now. My guess is as good as yours as to what it could be, but we should find out relatively soon, considering Nintendo will want to do everything they can to push the software side of the Wii U before the system is released. Any good guesses as to what the game might be?
