Well, being particular, that title shows people did want Kinect back then. Whether they still do or not can't be strongly supported by response to the original, new experience. It could be that, "people used to want Kinect, but now nobody wants Kinect," much like interest in Wii was incredibly high yet came to a stop. Or it could be, "people wanted Kinect when it launched, and want it as much/even more now." The only way to really argue that one way or the other would be current sales, methinks. Probably would need a Kinectless SKU to compare to.
A Kinectless SKU at anything approaching less the actual cost of Kinect (<>$100 at least), would crush the Kinect SKU in sales, almost assuredly.
Nothing more bluntly illustrates that Kinect 2.0 is currently a failure, than the fundamental economics.
Would be an interesting thought experiment to try to pinpoint at which price point discrepancy one thinks the +Kinect SKU would outsell the Kinectless...
I can't imagine that point being more than +$40, and I suspect you'd have to get down to perhaps +$20 to be sure of it. In other words if the Kinectless SKU was $399, I dont think the +Kinect SKU would be able to outsell it at more than $440, and probably less than that.
