Yeah I'm wary of the use, it's all good saying there wasn't enough of a reason to properly make use of it, but you've got at least 20 million people with one, and making a good use of it would have sold more to people waiting for good use. If 20 million people or however many people own it (remember it's the fastest selling piece of technology ever or something) isn't enough to warrant investment in making good use, I'm not sure how having maybe 5 million (at the most optimistic launch sales you will ever see) would smooth things over, there wont be any good use for a long time, by silly comparative logic anyway.
There's also too much bitterness from Kinect 1s uselessness which will only get worse as nothing comes killer app-y for users. What looks good Kinect wise on xbox one? Nothing? Remember your headset does voice commands (on games that wanted it) and there's no good use now either.
I'm all for it being mandatory to help creativity or persuade utilising it, but I thought millions of people owning one would have done it already. I'm still waiting for Kinect support in xcom and other turn based stuff, or bringing the RTS genre over. Stuff where latency isn't much of an issue.
That said, I really wanted a project natal, and I want Kinect 2 to be good. Do stuff people.
Trianglular Sandwiches advocate against remakes of games, except Halo MC collection and GTAV... and metro... and minecraft.
