Not surprising. Just look at all those Wii sales.
Wii is much cheaper though, and many casual gamers probably won't see a reason to buy another console with another gimmick for some more casual gaming.
The main point is: who wanted to buy Kinect, bought it already. I predict, that the sales will drop significantly. I doubt they'll hit the 5 million landmark before new year. In fact, I'll be surprised, if it'll pass 3 millions by that time.
