Ubisoft has revealed that it's beginning development on a new title for Wii U. Listings on Ubisoft Quebec's official Facbeook page indicate that the studio is currently hiring a Network Programmer and Senior Engine Programmer to develop a "AAA title" for Wii U.
Interestingly, Ubisoft communication coordinator Emile Gauthier posted on Twitter that the studio is also hiring a Tools Programmer for a "AAA MMO." While there's no indication that the two projects are connected, it's worth noting that both were posted on the same day. We've reached out to Ubisoft for clarification.
Ubisoft revealed at E3 that they're developing Assassin's Creed, Ghost Recon and Rabbids games for Wii U, as well as two new IPs. One of those IPs has been revealed to be Killer Freaks From Outer Space, and the other is currently unknown. At this point, it isn't clear which project these job listings are in reference to.
