so does this calculation make sense?
wii had a 17% boost and ps3 had a 7% boost since last week which most be due to the holidays kicking in. So if we assume that the 360 would have a normal 15% holiday boost then the rest of this weeks boost must be due to kinect meaning kinect sold a ballpark of 75,000 consoles to new users. therefore, since kinect kinect adventures sold 479,992 units then kinects demographics are:
~16% new users and ~84% sold to existing users.
...not bad, not bad at all especially for first week sales.
