the key is the us. As kowen pointed out, usa always buys more 360, while rest of world typically buys ps3. During the year, that leaves a majority of the world outselling the usa....but since usa is a big christmas country, the 360 tends to sell at a level that overequals the rest of world. Kinect does indeed help with this and their ms stores do a good job of attracting attention to kinect.
