The Russian Windows expert Wzor claim to have inside information about the release of Windows 8. According Wzor.net, January 2013 is the month that Windows 8 will be released. This makes sense, according to Microsoft’s earlier statements, about a launch around 3 years after the release of Windows 7.
Windows Server 2012 is also expected to be released in January 2013. Furthermore, he claims to also have information about Service Pack 2 for Windows Server 2008 R2 being released in the summer of 2012.
