Yeah, the COD franchise is a behemoth. It will be interesting to see what they pull out for 2011 since they don't have IW for bi-annual offerings.
As an aside, we recently bought a Kinect, and it's very fun. First video gaming where you get good exercise. It's pretty viral for those who try it, many stories about people buying a gaming console for the first time after playing kinect at friends'/relatives' place. Happened to me, first I showed it to bought a console package within a few days.
