The new Call of Duty from Treyarch is called Call of Duty: Black Ops and it will be released on November 9th 2010. That's official.Yes, despite Dean Takahashi's definitive statement that it was to be called Call of Duty: Vietnam, as per our earlier story casting doubt on that take given the historic naming conventions for the series, the game is officially named Black Ops.
There's very little new info for now. However, we stand by earlier statements that the game will be Cold War rather than strictly 'Nam based.
