Microsoft should once again release its next mainstream version of Windows about three years after the last, a roadmap obtained this week reveals. The schedule has the major revision, tentatively titled "Windows 8," launching in 2012 or about three years after Windows 7. It will purportedly keep in step with a rhythm developed by Microsoft that has Microsoft launching major releases four years apart, as Windows Server 2008 is considered a major release where its R2 upgrade and even Windows 7 are both treated as "release updates."
