i think a lot of you guys are discrediting Kinect before even trying it.
yes, the price is high.
yes, you need some space to play.
yes, direct sunlight on the player will cause tracking trouble.
after that, it works as advertised. and the only one of those three variables that will change is price (lower over time). i've played games with eyetoy and the xbox vision camera. kinect is on a different level. with kinect, tracking is much more accurate (thanks to the IR), and you have to remember that games don't have to be totally kinect centric. you can build a normal experience with kinect integration. a simple example i've used in the past is, imagine playing rockband like you usually would but, if you have kinect, your on-screen player will move like you do. while that isn't 'ground-breaking' or worth the $150, it's a simple example of how kinect can be used other than gimmick gesture games. i'm sure there are developers who are much more creative than i am and will find interesting ways to utilize kinect.
i don't know what most of you people expect. or maybe you guys just want something to complain about. but, after using kinect for the last couple days, i'm pretty sure it can have a place in the future and won't end up in the bargin bin. microsoft has put a lot of money into it and is standing behind it. this isn't something they're going to let go, at least, not easily.
