According to Wikipedia, David Kim accidentally let out that Call of Duty 7 was already in production .
The 7th edition of the game has been confirmed to take place in Vietnam (sadly, where we lost a war...), during the Vietnam War. This information was found from a person currently working in Treyarch.
The game would probably be released in November, 2010. The game is certainly going to come out on the PS3, Xbox 360, and the PC. The Wii version is still waiting approval...
It’s confirmed! The PlayStation 3 is now available for $299. Yes, NOW! Today, Kaz Hirai also announced a new, slimmer form factor 120 GB PS3 (available September 1st). SCEA President and CEO Jack Tretton shows off the new hardware in this video.
I do not claim the writing or video as my own.
