I believe MS is taking an approach of focusing directly on the so called casual gamers first with Kinect and then will reach back out to the so called hardcore gamers later on. I believe they have in the labs a add on controller to go along with Kinect for movement and a trigger. They could have came out with one at launch, but choose to go the completly controllerless route to not cloud the message of Kinect. Next year you will see Kinect with extra stuff and games that will be more interesting to hardcore gamers.
It is also important to point out that the area MS wants some of the cut in are the fitness/casual sports gamers. Look at the software charts each week and Wii Sports, Wii Sports Resort, WiiFit and now Just Dance are in the list nearly each and every week. It isnt because they are phenominal software it is the Motion control and the allure of people moving. Please dont argue that those games sell because of the software. Wii Sports is fun because of motion. If you replace the motion with a button the games would be awfully boring. Kinect Sports, Kinect Adventures, UBISofts Your Shape and Dance Central all look like high quality titles in the casual genre that are going for the casual crowd.
Its libraries that sell systems not a single game.
