Microsoft's Marc Whitten just lifted the hood on the Xbox One's technical specifications. In short: 8GB of RAM, USB 3.0, Wi-Fi Direct, a Blu-ray disc drive, 64-bit architecture and "practically silent operation".
Kinect 2.0 also gets a substantial upgrade. Whitten promised the integrated camera will have a wider field of view, and the sensor will be able to detect more joints, to include rotation of wrists and shoulders. "When you are exercising it can read your heartbeat."
