The XB1 wasn't marketed as a gaming machine, but rather as the new center of your living room entertainment experience, and the Kinect was supposed to be a big part of that: using both speech and gestures to easily control your entertainment. VR experiences [you desire], require proper VR friendly controls [also VR friendly physical space, and VR friendly PCs]. Occulus has had several successful demos without the use of VR friendly controls, with some using just a mobile phone as the backing CPU/GPU. It's still yet to be determined if initially the streamline experience that comes with the base Occulus/GearVR setup is what the market wants, compared to the more fully immersive experience that comes with the Vive (at the additional cost). With a newborn at home, I don't have the luxury using VR, but I am excited to see how this all shakes out. While my personal preference is for something I can use while at my desk (270 virtual desktop?), I also see how compelling a fully immersive VR experience can be.
