Call Of Duty 7 already being made?

Call of Duty 6 (Sorry "Modern Warfare 2") has only been unveiled in the last month with tid-bits of info and one video out in the wild and a long way off a release date. But Call of Duty 7 is already in the works from what Senior Animator Divid Kim has been stating :

"I am currently on my second title as a senior animator in the games industry with Activision / Treyarch on Call Of Duty 7. Previous to that I specialized as a previsualization artist for various productions."

Clearly dont expect ANY details for a while but it looks like the Series is here to stay!
