Call of Duty: Black Ops

Call of Duty 7  (working title) will be the seventh main installment in the Call of Duty series. This information was leaked by David Kim, a senior animator at Treyarch. The game is to be set in the Vietnam War during the 1960s, and will be released in November 2010. Not much else is known at the moment, although it is hinted that the game will be set in Vietnam and the Cold War.

It is currently being developed by Treyarch.

In a recent article in CVG, Activision's CEO Mike Griffith admitted that Call of Duty 7 is not expected to exceed sales of Infinity Ward's Call of Duty: Modern Warfare 2.

In another recent article in CVG, it was said that a "Activision insider" said that Call of Duty 7 is titled "Call of Duty: Black Ops". It will be set in 'recent history' (between World War II and the present day) and will feature missions in Cuba and South America. Among these, it says that the player takes control of a British SAS member during the 1980 siege of the Iranian embassy in London. However, this has not been confirmed by Activision or Treyarch, therefore it may turn out to be false.

Everything that is true or false will be revealed in May in Official Playstation Magazine, says an article here.

Many people also think that the website GKNOVA6 has something to do with Call of Duty. If this is from Call of Duty 7 it is implying it is set during the Cold War, which subsequently complements the rumour of the Iranian embassy siege.
