With Treyarch back in the driver's seat for this year's Call of Duty , maybe it made sense to expect a sequel to Black Ops .
And evidence has surfaced to support that theory. First, a Treyarch employee accidentally lists "Black Ops 2" on his resume (as outed by Joystiq ) and then, a French source found a listing for "Call of Duty: Black Ops 2" at Amazon France's website.
Both the LinkedIn resume and the Amazon listing have since been removed, but it may be too late. Activision recently confirmed we'd see a new Call of Duty installment in 2012 (no big shock there), and sequels have proven quite lucrative for this franchise. Just ask Infinity Ward. Besides, Black Ops set a whole bunch of sales records (before Modern Warfare 3 promptly broke them a year later), so a Black Ops follow-up would make perfect sense.
Personally, I'm just waiting for a new CoD engine. Seriously.
