When exactly DOES Hyper-V get live migration?

I'm having a hard time consolidating and then parsing the announcements made by Microsoft today about Hyper-V server virtualization.  Besides the reduction in price for an analog to VMware's ESX 3i, they've announced live migration will arrive ... but it's not clear when.  According to Virtual.info, Mary Jo Foley at ZDNet seems to imply that hot server migration will appear with Windows Server 2008 R2 ... now officially slated to appear in 2010.

I can't quite connect the dots.  Can anyone provide clarity as to a likely timetable for the incorporation of live migration into Hyper-V?

Microsoft said on Monday that it now plans to offer its server virtualization product for free.

Ahead of a virtualization event in Redmond, Wash., Microsoft said that its Hyper-V Server 2008 will be released within 30 days and be available at no cost via the Web. The software maker had planned to charge $28 for the product.

Also on Monday, Microsoft plans to show off a live migration feature that will be part of the next version of its Hyper-V virtualization technology. Live migration allows companies to move a running virtual machine from one server to another.


Techworld's write up of the Hyper-V announcement seems to shed some light.  Based on this comment, Windows
Server 2008 R2 is due out in 2009, not 2010.  It's worth pointing out, however, that MSFT has already been willing to release initial versions of Hyper-V on a schedule that's seemingly independent of the Windows Server 2008 schedule.  I suppose there's a chance that it could, once again, establish a separate schedule for the release of Hyper-V live migration.

Neil Sanderson, head of virtualisation
for Microsoft UK said that the company had previously announced Hyper-V
as part of Microsoft Server 2008 but that is was now launching it as a
standalone product. In addition, he said, the company was dropping the
$28 (£16) fee that had been previously been announced for the
standalone version.

Sanderson acknowledged that Microsoft was
some way behind VMware but said that there was a low user base. "We're
still in the early days of virtualisation - IDC is predicting 25
percent of the market by 2010 - and there's still everything to play


But it's not just Hyper-V itself; Sanderson highlighted Virtual
Machine Manager as a product that will have quite an impact. The
management product will offer users support for VMware in addition to
Microsoft and Sanderson believes that is this interoperability that
will be key. "Microsoft has been working closely with the likes of
Novell and Citrix to ensure support for non-Microsoft technology."

Answering criticism that the absence of a live migration feature
would hinder the take-up of Hyper-V, Sanderson said that this was being
addressed and that a demo version of live migration would be featured
at the US launch. "We expect it to be included as part of Windows
Server 2008 R2 next year," he added.
