From Microsoft Watch: The names have changed. But the plan is still the same. Microsoft is now going to release Virtual Server 2005 R2 (the product formerly known as Virtual Server 2005 Service Pack 1) before the end of this year. It is still planning on rolling out a new version of Virtual Server in 2006, but is no longer referring to that product as Virtual Server "Version 2." Microsoft is still working to integrate the Virtual Server "hypervisor" technology into Windows Server, some time after Longhorn Server ships in 2007.
