Talking Kinect With Kudo on GameInformer.com includes a wacky quote, as pointed out by Computer and Video Games, as Kinect creator Kudo Tsunoda says: "hardly anyone plays first person shooters on the PC anymore." Here's more of the quote:

Halo did an awesome job of building a first-person shooter exclusively for the console, and now hardly anyone plays first person shooters on the PC anymore. It’s all about the console. And I feel it is the same with Kinect stuff. If you are constantly trying to take something that is made for a controller and port it over to Kinect, it’s not going to be a good experience because it is made for a controller. If you take the time to build it for Kinect from the ground up, however, you can make something that is a very new experience, but lots of times even more fun than it was before.
