in Anlehnung an den Vista Wikipedia Thread hier nun aktuelles zu Windows 7, ehemals Blackcomb und Vienna:
Windows 7 - Wikipedia, the free encyclopedia
Windows 7, (formerly codenamed Blackcomb and later Vienna) is the working name for the next major version of Microsoft Windows as the successor to Windows Vista. Microsoft has announced that it is "scoping Windows 7 development to a three-year timeframe", and that "the specific release date will ultimately be determined by meeting the quality bar." Windows 7 is expected to be released in January 2010.
Windows 7 will ship in both client and server versions with the client versions available in both 32-bit and 64-bit editions. The server version of Windows 7 will be called Windows Server 2008 R2 and will be 64-bit only.
Der Name für die Serverversion steht soweit fest: Windows Server 2008 R2. Aus Serversicht wird es also nach heutigem Stand ein Minor-Release werden.
