Yeah, sure. Everyone will want to wave their arms and speak to it.
I tried using it. Did not like it in the least. I felt like a loon waving my arms around like that.
Thats where the new functionality comes in. The Camera is better, and the microphone is better. The Kinect can now Track controllers, determine heartrate, operate in a pitch black environment and be able to filter out even the most noisy of rooms.
Developers can use the heartrate function in it (something everyone drooled over when Nintendo announced the now dead vitality sensor) to enhance horror and shooters. With the higher quality camera, developers can track more subtle things like a quick shake of the body (as used in DR3 to throw off zombies who jump on you instead of having to mash a button) or a persons thumbs. The Kinect can now track the controllers so you can do things with those (or at the OS Level how it will auto sign in to whatever controller you pick up). And the Microphone is not only much more sensitive to sounds, but it does a much better job at filtering out background noise to only hear you, this way your not repeating things over and over again for it to pick up.
They do so much more with the new Kinect. Developers will be able to make Kinect a large part of games because it is part of the standard package and not something only 10 Million people have. Everyone will have one so more things will be crafted with it. Its just going to become something that everyone expects.
