Microsoft:

Microsoft said it has decided not to move forward with a Universal version of Virtual PC at this time. However, it will continue to provide support to existing Virtual PC customers.

"Developing a high-quality virtualization solution, such as Virtual PC, for the Intel-based Mac is similar to creating a version 1.0 release due to how closely the product integrates with Mac hardware." Microsoft said.

Also, Microsoft said it will be discontinuing support of Visual Basic scripting in the next version of Office for Mac.
