It has been dead for a while. D4 was probably the last title of note to release with Kinect integration, and it didn't do well. They took out UI nav via Kinect with the 2015 dash update. They're dumping Xbox Fitness (basically the last thing using the Kinect for actual interaction) at year's end for free content, and mid-2017 for paid stuff. They wrecked voice commands by turning "Xbox" to "Hey, Cortana." Now, instead of "Xbox On," you get the pleasure of "Hey, Cortana, Xbox On," while agreeing to let MS data mine everything you say to the console (as such, I have stopped using my Kienct for voice).
