I'm surprised no-one has brought up "Eyetoy" for the PS2 as "Kinect" to me is more like this than the Wii (Although, Kinect Sports... REALLY? :\ If you're going to rip-off the Wii at least make the name original haha) I think that it will just be an upgraded version of the Eyetoy. Don't think I'm going to buy it but if any of my friends do then sure, I'll have a go just to say I've tried it.
There were, like, two games that used the eyetoy and that was a generation ago.
As for the Kinect, judging it by Microsoft's press conference, having little to no control and doing with my hands what I can already do with an analog stick isn't very appealing. You can't use that for gaming as far as I see. IMO, Motion control needs to add to the already established game controller. It helps enhance the immersion and things like that. When that's all you have, and considering it's so young and so flawed (Forza: No acceleration or deceleration. Star Wars: Flail arms, dash, rinse, repeat.) it can't appeal to anyone, especially not their
CORE DEMOGRAPHIC. Think about it, Nintendo was making the Wii to go with a new strategy to make money. Their Blue Water strategy is paying off and the hardcore fans, while upset at the beginning, just look at their last couple E3 conferences, are now happy. New Donkey Kong Country, new Kirby, new Metroid, their happy. The Kinect can't do that. No matter how hard it tries, it has one market and although that might pay off for a while, ignoring your core demographic I find to be disgusting. Microsoft is making the mistake that Nintendo made. Appeal to the casual market and
only the casual market and throw your core demographic a Halo shaped bone every now and again. Nintendo learned from that mistake and, to remedy this, have made bridge games. Games that make both parties happy (Mario Kart Wii and NSMB Wii are both perfect examples). Microsoft probably isn't going to do that, IMO.
To sum it up:
