It is official, it is Christmas in July for many MSDN / Technet subscribers. The official RTM version of Windows 7 will be available for download on MSDN / Technet on July 13th.
Wait… I thought it was supposed to be released on October 22nd?
The October 22nd date is the date it will be available in stores. The July 13th release is the same version that will be cut to the manufacturers. It takes the manufacturers time to get their stuff in order so units can start shipping (usually about 3 months). Thus pending any major bugs, the July 13th release is the official version.
