Also, at the TechEd Keynote, I demonstrated VSTS for Database Professionals working with DB2.  The first step in the process is a release we are working on now called the VSTS for Database Professionals 2008 GDR (I’m not going to waste your time trying to explain what a GDR is – just think of it as an update – not too much unlike a service pack).  This GDR will be the initial trial of a bunch of extensibility work we’ve been doing.  The first proof point is that SQL 2008 support is implemented on top of this extensibility and then DB2 and others can follow after that.  There are many other things in the GDR release that I think you will like.  Gert has written about them here: http://blogs.msdn.com/gertd/archive/2008/06/03/vsts-2008-database-edition-gdr-june-ctp.aspx
