Quoting from MacMinute:
The next version of Virtual PC has been pushed back until October. An e-mail sent to MacMinute by Microsoft notes that: “As you may know, Virtual PC 7 ships with Windows XP both in a box by itself as well as in the Office 2004 for Mac Professional Edition. We are waiting for the release of Windows XP SP2 in order to offer the most recent, most secure version of Windows XP to our Virtual PC for Mac customers. Windows XP SP2 release has moved to August, which has impacted our schedule. Based on this, we anticipate that Virtual PC 7 with Win XP Professional and Home will release to manufacturing in September and be on store shelves by early October. Virtual PC 7 with Windows 2000 and the Standalone and Upgrade versions will be available a few months after this debut. Should the Windows XP SP2 release date change the Virtual PC 7 availability date will change accordingly.”
