Rumour's had it for some time now that a Wii U version of Call of Duty: Black Ops II would be coming out around the system's launch at the end of 2012. The game is slated to come out on November 13, 2012, for PC, PS3, and 360.
Now an apparent oopsie on a Treyarch employee's resume has indicated that the company has been involved in quality assurance for a Wii U version of the game for some time. (I won't be linking to the tester's Linkedin resume, as having his name all over the internet for spilling the beans might hurt the poor guy's career.) Of course, this isn't the same as an official announcement, but it certainly adds fuel to the rumours that have been circulating, and may feel like vindication for those who said the Wii U Pro Controller was created to get the Call of Duty franchise on board Nintendo's new console.
We'll have more for you as it develops.
