A road map showing some of the phases of development of the future operating system Microsoft has confirmed the revelation made last October by the company itself. Windows 8 is scheduled to arrive in a little over a year, in 2012.

The document shows the progress of the second part of the design of Windows 8 began in September and ends this week. It includes some design, integration, and bug fixes to make way for finalizing the third phase of development called "Milestone 3" (M3).

If the third phase M3, which begins Feb. 28 takes as much time as the previous one, we might see a beta of Windows 8 arrive in the fourth quarter of this year.

Approached to the new Windows 8 concern the compatibility with touch pads, a new interface, an anti-piracy or impetus for PC games.
