As previously mentioned, Windows XP Service Pack 2 has been delayed until at least August. Today, Microsoft confirmed the consequent delay of Virtual PC 7. The Microsoft Macintosh Business Unit states that if SP2 does ship in August, Virtual PC 7 with Windows XP SP2 will be available in October. However, other versions of Virtual PC 7 (with Windows 2000, or without Windows) will not be available until several months later.
Virtual PC 7 is necessary for those running G5 machines. Virtual PC 6 is incompatible with the Power Mac G5, and will also be incompatible with the upcoming iMac G5.
