I'd rather contract AIDS from having intercourse with a plant I found in the midst of the fecal matter that was known as the Wii. If there was a chance it could be used for serious gaming then it would strike me as potentially useful in the world. But, because all it has is Kinectimals, it won't be. The closest thing that I've seen that could be enjoyable was the star wars game and that's just 'wave your arms around like you're getting attention of a ship' then force forward, it won't be any good.
No, motion sensing technology is not ready to be incorporated into the gaming industry any more than it has done. Heck, I'd say the Wii is better for serious gaming than Kinect.
Edit
...child of eden seems kinda cool though.
