Just spotted this publicly available webcast on 4th October 1PM-2PM PST (9PM-10PM UK) which should provide a great opportunity to ask questions about where we are heading with the Windows hypervisor technology.

TechNet Webcast: Microsoft Virtualization Roadmap (Level 300)
Mike Neil, Product Unit Manager, Microsoft Corporation

Today's information technology organizations are under pressure to reduce costs and prioritize spending on new equipment. Virtualization technology is emerging as an effective way to increase both productivity and deployment flexibility. Virtualization technology can play a key role in uncoupling workloads from server resources and enabling a dynamic and automated datacenter. Microsoft is investing heavily in the next generation of virtualization technology and the management tools that will drive it. This session presents Microsoft's virtualization roadmap and strategy, starting with Microsoft Virtual Server 2005.  We then discuss the Windows hypervisor technology, which will be incorporated into the next release of Microsoft Windows Server.
