After all of the press behind the release of Windows 8 in late 2012 it may now be that the world will be getting its first look at the new Windows operating system before too long. The new operating system is currently being worked on under the code name "Threshold".
According to an unnamed source the "Threshold" or Windows 9 reveal will occur on September 30th, it is also suspected that Microsoft will release a preview version alongside or shortly after the announcement. This will follow in the trend of Windows 8 releasing a developers preview months before the official release of Windows 8. At the moment Windows 9 is expected to be released Spring 2015.
