The source of this supposed leak is CNBeta, a site with close insider ties at Microsoft Corp. (MSFT), which gained respect by accurately leaking a number of early Windows 8 details.

Other info from the site includes suggests that Microsoft will further flatten the UI on the desktop (think the Metro/Windows 8 UI style), the taskbar/desktop will get tweaks, the price will be low (or free), and the new kernel version number will be v6.3 (corroborated by other independent reports). The final remnants of the Aero UI, which was a staple of Windows Vista and Windows 7 is also being bid adieu, like the Start button before it.
