A quick scan through the Microsoft Learning Exam Catalogue shows that a new MCITP blanket certification could be on the way.  So far details are scarce, but both 70-669: Windows Server 2008 R2, Desktop Virtualization and 70-693: Pro: Windows Server 2008 R2, Virtualization Administrator list themselves as counting towards MCITP: Virtualization Administrator.

It wouldn't be a huge stretch of the imagination to imagine that 70-652: Windows Server Virtualization may feature as part of the final certification.

We'll update you further as more details emerge.
