Nobody owns depth detection concept. MS owns a custom version of a clever implementation designed originally by a 3rd party. If I were Sony, I'd try to reduce costs using a single RGB+IR camera instead of two separed RGB and IR ones like Kinect. I'd also try something different from IR pattern projection and detection. Let's not forget that depth detection through the PSMove Dildo saves Sony additional efforts in many cases, but a camera with better depth detection is necessary if Sony doesn't want Kinect to have almost the exclusive for hands-free motion detection games. MS needs a stick for some games, Sony and Nintendo need an advanced depth detection camera for some others, and shame on Ninty and 3rd parties for not having developed more games for Balance Board, as for skiing, snowbording, yoga and some other sports and fitness games, posture and pressure detection are better than camera and/or stick based motion detection (BB + a stick inserted in a handlebar could be the definitive control scheme for bike simulation at an acceptable cost, without having to buy some expensive, niche and cumbersome bike-shaped input device)
