Alleged specs for the next iteration of Microsoft's Kinect sensor have popped up on VGLeaks. The new Kinect will be included with the next Xbox, according to the report, and it seems to outperform its predecessor in nearly every way. It packs a much larger field of view (70 degrees horizontal by 60 degrees vertical, versus the current 57.5 x 43.5) and a dramatically higher resolution (1920x1080 versus 640x480). The unit also features significantly lower latency (60ms versus 90ms), conceivably giving it a much faster reaction time.
It will apparently ditch the tilt motor seen in the current Kinect, as the larger field of view should accommodate most play spaces. For example, the new Kinect should be able to detect a 6' tall person at just over five feet from the television. As previous reports have suggested, it will also be able to recognize more minute details, such as whether a hand is open or closed.
For what it's worth, in the absence of verification, the tech wizards at Digital Foundry find the leak plausible, though it may not be the most current information. Furthermore, the information does seem to match up with previous reports, specifically the sensor's improved resolution and its ability to detect much finer details.
