The 56 page PowerPoint document that leaked the next-gen Xbox details over the weekend has been removed from the website it was leaked to.

CVG report that the sensitive documents supposedly revealed that the Xbox 720 will be released for the 2013 holidays with 4 to 6 times the power of the current Xbox 360.

The documents also stated that the console would be blu-ray capable, ship with the next-generation of Kinect and the recently announced Microsoft SmartGlass.

Covington & Burling LLP attorneys, who provide their services to Microsoft, swiftly had the documents removed. The document authenticity is still in question as the it appears to have been written in 2010. The price would certainly be in question if the document was written in 2010 as fluctuation has been anything but normal, therefore forecasting would possibly be out.
