UPDATE: CVG can confirm that Activision has pencilled in a November release date for the Call Of Duty: Black Ops. Black Ops will include gameplay in the late 1960s, during the Vietnam War.
Following this week's rumours, a senior UK trade source today told us that the Treyarch-developed Call OF Duty: Black Ops is scheduled to arrive a full 12 months after last year's Modern Warfare 2.
They added that much of the game would be set during the Vietnam conflict - and takes particular influence from classic movies Apocalypse Now and Platoon.
"It's going to be November again - just as with World At War and Modern Warfare 2," they told CVG.
"Activision believes that it can own Christmas 2010, just as it has in the last two years.
"Development is on course - and Treyarch have been told the game must be ready to hit shelves before the gifting season."
Activision declined to comment when contacted by CVG.
