Sure, they made Call of Duty 2: Big Red One, Call of Duty 3, and Call of Duty: World at War, but what have they really done for the franchise?
Anyways, Treyarch is making a new Call of Duty game for us, titled Black Ops
(with the obligatory Call of Duty in the front of it.)
According to the internet, Black Ops will be taking place in 'Nam, and you will be a black operative
going behind enemy lines.
A teaser trailer on GT found here
shows someone obviously being revived, with many fast cuts and takes between other stuff.
