Xbox One has been sized up by a 'verified' Xbox One developer over on Reddit. Kinect's girth and cable length have also been noted, which should come useful to those fearing a living room upheaval.
The stats were posted on Reddit by XboxOneDev, who is listed as a verified developer on the console.
They go as follows:
13.1" x 10.8" x 3.1"
33.3cm x 27.4cm x 7.9cm
Kinect 2 (LxWxH):
9.8" x 2.6" x 2.63"
24.9cm x 6.6cm x 6.7cm
Kinect cable approx. 9.5 feet (2.9m) long
The post adds that the measurements were, "Measured with a tape where the precision is 1/8 so all values are an approximation."
So it's definitely bigger than an Xbox 360, but you didn't need tape to know that.
Xbox One is out November 22 in several territories. In the meantime, Microsoft has denied rumours that Xbox One will run Windows 8 apps.
