Wikipedia's Kinect article describes the Kinect for Xbox[3] One: 'wide-angle time-of-flight camera', 2 gigabits of data per second, three times the fidelity, 60% wider field of vision, six skeletons, 25 joints, heart rate and 1080p colour camera.
Xbox Wire's own announcement states the standalone Kinect sensor becomes available "beginning in October 7" at $149.99, matching the pin's stored 6-7 October 2014 window and $149 price almost exactly, published 27 August 2014 ahead of launch.
GeekWire's own headline, "Microsoft to sell standalone Xbox[3] One Kinect sensor for $150 this October," corroborates the pin's October/~$149 claim and shares Xbox Wire's 27 August 2014 publish date, though the article text itself could not be retrieved (403 error).
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
