Just stumbled across a set of (sales/business) presentations on the new Hosted Messaging and Collaboration 4.0 solution (We are actively working with customers on this release, but all information is under NDA until the final release in April).
The Hosted Messaging and Collaboration 4.0 event, held by Microsoft’s UK Software as a Service team, covered the new release of HMC version 4, which is based on the release of Exchange and Sharepoint 2007.

You can find a bit more information on the Microsoft Global Hosting Summit 2007 (Held last week) and in the two videos in the press release from the summit -
Hosted Messaging and Collaboration v4.0 - Announced by David Thompson, Corp. VP, Information Worker Enterprise Group, Microsoft Corp.
Microsoft Solution for Windows-based Hosting v4.5 - Announced by John Zanni, Director of Worldwide Hosting, Microsoft Corp.
Personally I think it's a very interesting release, but I look even more forward to the release where Office Communicator Server 2007 is included (Enabling a full Unified Communications experience).
