A document leaked from Microsoft which supposedly details the next-generation Xbox has been removed from a document-hosting website.
The 56-page presentation lists various features for the 'Xbox 720'.
Datated from mid-2010, the presentation lists features like Blu-ray support, 3D glasses, cloud-based gaming, Xbox SmartGlass connectivity with tablets and phones and an improved version of Kinect.
The document also says the new console will have 1080 output, and will be priced cheaply at $299 from 2013.
The new hardware will also include improved voice recognition and stereo imaging.
Microsoft promises six times the performance of the current Xbox, but the number of processors and the exact CPU have - or were - yet to be decided.
The console as it appears in the document is thin, black and looks more like a traditional DVD player than the existing Xbox.
But the document has now been removed, "at the request of Covington & Burling LLP".
Microsoft will unveil its latest innovation in a product announcement from Los Angeles on Monday, but it is unlikely to be related to the future of Xbox, sources say.
