The evidence that Activision is in fact working on Call of Duty: Black Ops 2 is mounting. As spotted by Joystiq, an employee of contract art studio Nerve Software listed Call of Duty: Black Ops 2 on his resume as a title presently in development.
Nerve Software has worked with Activision before. The studio provided art for the original Call of Duty: Black Ops, as well as James Bond film tie-in Quantum of Solace. Both games were developed by Treyarch.
This is not the first mention of Call of Duty: Black Ops 2. Earlier this week, Amazon's French website reportedly listed the game before scrubbing the listing.
Activision confirmed in November that a new entry in the Call of Duty series would be on shelves this year, but the publisher has not confirmed its developer, era, or setting. Treyarch developed the original Call of Duty: Black Ops, which was set during the Cold War. It featured familiar political faces like John F. Kennedy, Fidel Castro, and Robert McNamara.
