Kinect itself does nothing of the sort - though full motion body tracking in and of itself could be very powerful with VR. As has already been accurately stated in this very thread, Kinect's latency is simply too high. 60ms is over double the maximum amount of latency that is generally agreed as tolerable for a VR experience. Kinect 2.0 was not future-proofed - it was built to power the experiences that Microsoft promised Kinect 1.0 would deliver, and little else. Software improvements could be made, sure - but decreasing latency by 66% on just software? Microsoft aren't that incompetent, regardless of what we might like to think.
It's evident that Microsoft intended for the every-man to believe that Kinect was magically powering the Xbone's "amazing" voice command system, and not question the fact that the vast majority of Kinect's function is being entirely ignored not only by developers, but Microsoft itself. Full motion body tracking is amazing technology - it really is. However, it's applications in the console gaming industry are so few as to be not worth mentioning. The utter mistake of its inclusion is Don Mattrick's legacy.
To answer the OP: is Kinect worth the investment for Microsoft? Not really. Kinect 1.0 had a $500m marketing budget. Its sales probably paid for its R&D and marketing. The cost of 2.0, however, is unknown. Microsoft spent $100m on the controller, and what it produced has only one agreed upon improvement: trigger feedback. It's safe to say they spent more than that on Kinect 2.0, which has only slowed down the Xbone's adoption rate due to price inflation, costing Microsoft valuable early adopters and losing market-share gained by the Xbox 360.
Coupled with a near-total lack of titles for Kinect, and it's evident that Microsoft's R&D produced nothing more than an expensive anchor that drags the Xbone down by preventing competitive pricing, and pushing a focus on entertainment that too few people actually want. Kinect 2.0 is an interesting piece of technology, no question, but its not a consumer product, and it brings nothing of any real value to the Xbone that couldn't be replaced with a pack-in microphone.
I suspect Elop performs a daily "Curse you Mattrick" ritual before beginning each business day. If I'd been left with the Xbone and the problem of Kinect, I know I would.
