So that 2.5 million figure is likely sold to consumers and not shipped since the 1 million figure was revealed to be "sold thru to consumers."
If that's the case then black friday Kinect sales must have been MASSIVE.
My own personal experience saw every single 360/Kinect bundle sell out at all stores in my area. All the 4gb and 250gb. There were some standalone kinects available as well as some standard 4gb/250gb consoles, but not many.
The main focus should be on all of those Kinect Bundles being sold out as that clearly shows Kinect is a big hardware mover to new owners this holiday. I don't know how many parents I saw come into gamestop asking about Kinect.
