not happening
Kinect had an initial boom, but Move is gaining speed and PS3 is still outselling the 360 either way.
We have the majority of friends we circle with owning 360s, with 5 of them owning both that and a PS3 and only 2 of us having a PS3 and no 360 (and we added ourselves to that pool just this past Monday, had only a beat up PS2 previously we had not powered on in about a year). After playing hours upon hours of both Kinect and move, it is readily clear move is the far superior platform. Lack of buttons to push is a big issue for expanding into other game genres, and the system 6-9% overherd of full body motion tracking vs the PS3's 2% impact, on a processor that's less powerful to begin with, does translate into a noticable lag. plus, move support is being added to retro games, but Kinect can not be.
In every house that has X-Box and PS3, the PS3 is the main system, 360 only powered on for exclusive titles. Every house that got kinect stopped playing it after 45 days tops, 2 returned it after a few weeks, but those using move are actively playing and buying more games for it.
having just got a PS3, my only disappointment with it is that it lacks native streaming support not only for iTunes (which was expected), but it doesn't talk to WMC either, just DLNA alone run by WMP, not WMC. BluRay was an afterthought, little more than a bonus feature, we bought it for the Sony native content, the streaming apps that don't require membership in Live, and move.
