Microsoft has discussed the improved viewing angle of the version of Kinect that ships with Xbox One in the past, but without providing specifics. According to this leaked manual, which was posted on NeoGAF and can be seen here, the minimum distance required between players and Kinect is 1.4 meters, or about 4.59 feet. That's a marked improvement over the suggested 6 feet/1.8 meter minimum distance for the Xbox 360's Kinect sensor, and should make using the device in small rooms more feasible. The manual also notes the Kinect should sit somewhere between 0.6 meters (1.97 feet) and 1.8 meters (5.9 feet) above the floor.
The contents of the box -- the system itself, Kinect, a headset, two AA batteries, a manual, a controller, a power cable (which comes in two parts, as with Xbox 360), and an HDMI cable -- are also listed.
The information regarding Kinect is of interest to every Xbox One buyer; while the device is no longer required for the system to function, as was originally the case, Microsoft has been adamant that the system will never come without one. From what we've seen, this version of Kinect does appear to be an improvement over its predecessor.
Xbox One is scheduled for release on November 22 in North America, Europe, and Australia.
