A roadmap timeline slide shown by Microsoft at the 2009 Professional Developers Conference shows that a product code-named Windows 8 is scheduled to be released sometime around 2011 (Beta) and 2012. Development and other aspects of Windows 8 have not been detailed in public, although job listings have mentioned improved functionality for file access in branch offices.
A Microsoft KB article confirmed that Windows 8 is the next version of Windows. The article has now been changed to remove references to Windows 8.
