"Microsoft today made a surprise announcement that Hyper-V, code-named "Viridian," is available as a public beta with Windows Server 2008 RC1 Enterprise edition. Originally, Hyper-V was scheduled to ship with the RTM version of Windows 2008 in Q1 of next year.
The initial version is restricted to the 64-bit version of Windows 2008, and is currently only available in an English-U.S. version. The final version of Hyper-V is expected to ship about 180 days after RTM, Microsoft has consistently stated."

The Hyper-V site also contains links to whitepapers, a webcast series, FAQ, TechNet info, and the team blog (good info, more videos).
