“Today, we have three studios working on Call of Duty. We have Infinity Ward, which made Call of Duty 2, Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare 2. Then we have Treyarch, which will be releasing a Call of Duty game in the fall of 2010. Treyarch also developed Call of Duty: World at War and Call of Duty 3."We try not to be too opinionated here, but when you see a publisher like Activision hump a series like Guitar Hero until it's a cold, dead corpse, it's hard not to worry about a definitive franchise like Call of Duty.
“And, most recently, we’ve added Sledgehammer in the Bay Area. We haven’t yet announced the content of their game, but it’s going to be an innovative take that will further broaden the audience for Call of Duty.”
Infinity Ward was a developer dedicated to the game, working on it for as long as necessary and brought us the best titles in the series. Now Activision has fired the studio's two bosses, lost most of the key staff, handed over development of a third COD title to an upstart studio and maintaining development of titles from Infinity Ward and Treyarch to release 3 titles in a year or two.
You can't help but feel a sense of 'oh that sells, lets make more of it and sell it until it dies, then move onto something else'.
