The Kinect, once such an integral part of Microsoft's Xbox One story, just lost a big toehold. You no longer need the depth sensor for Xbox Fitness, a key non-gaming app. The device brings gamification to workouts and forces you to think about form, so the app is more like a streaming service without it. However, dropping the requirement certainly opens it up to more users. Folks who compete with friends might also be disappointed to know that non-Kinect rivals still get a score just for watching the videos. Kinect users can score higher, though, and new workout titles will continue to support the camera. There's no word on whether Microsoft might offer smartphone body tracking like it does with Just Dance Now.
