Looks like PDC is going to be huge this year and if you get a chance check-out the three BizTalk Server sessions.  We have been asked by the organizers to talk strictly about futures so there is a bunch of new content.  However, if you want to play with BTS04 then definitely check out the hands-on-labs.

I've been working frantically to get an "Indigo" and BizTalk Server demo working.  It seems to be running "reliably" now :).  I warn everyone coming to my session that I have 2.5 hours of content and an hour to deliver it, but I know all you PDC attendees are hard core.

Here is the complete list of BizTalk Server Sessions:

This session demonstrates an early prototype for a scaled down lightweight, re-hostable orchestration engine. Orchestration is being enhanced to provide programmer friendly APIs accessible to any language, enable even more complex flows through deep integration with rules, and tighter integration with people. This engine is ideal for such functions as: performing tasks inside WinFS, workflow inside STS or page flow in ASP.NET or your favorite scenario.
