Microsoft finished Windows Server 2008! This is very cool! The new status of 2k8 is RTM which means that it is Releases to Manufacturing.
You can download the Server at the Technet and MSDN.

But... What is about Hyper-V? Hyper-V is included in the bits but its still a beta. So, be carefull in production environment.

The Release of Hyper-V is scheduled for the next 180 days...
