I'm not saying I disagree about the points you are making, but links does not equate to sourceable facts. The trade show Kinect displays were also immensely more functional than the released products. The Oculus Touch is not a real product (yet). Same goes for the roomscale tracking. There's no point in discussing the capabilities of a product before it's manufactured at scale, with all the cost-cutting that entails. Trade show demos really does not say anything unless the product on show has gone to production.
