A new leaked document suggests that Xbox Surface will consist of a stationary computing device and a tablet computer, reports Shifted2U.
The tablet device will apparently feature a 7" multi-touch LED screen with a resolution of 1280x720.
The stationary device, meanwhile, will contain two IBM POWER7 SCMs, each with six active cores.
It will also feature a custom 28nm AMD GPU, as well as a 250GB optical disc drive, which can be expanded via USB flash memory.
The original Microsoft Surface was a table-top product built by Samsung and Microsoft, aimed at businesses and education facilities.
Another Xbox 720 leak suggests that the upcoming console will support cutting-edge 3D technology through Kinect 3D Glasses, codenamed Fortaleza. This service will be implemented over WiFi in 2014, and via 4G the following year.
Kinect 2.0 will reportedly launch with the console, featuring improved tracking and dedicated processing, and with better play space and high definition.
The console is supposedly six times more powerful than the Xbox 360, and will include a Blu-ray optical drive and "always online" technology.
According to the document, the Xbox 720 and its Kinect 2.0 sensor will be released in 2013, priced at $299 (£190).
