Have you tried Orcas Beta 1 yet?

If you haven't heard yet, the Orcas Beta 1 VPCs are available for download now!  We've added a lot of new features for TFS in this release including continuous integration, build scheduling, and better extensibility for Team Build, folder diff and annotations in version control, lots of performance improvements & scalability enhancements, etc.  Beta 2 will include even more new features including the ability to upgrade from previous releases.  In the meantime, please dig into Beta 1 and report any bugs you find!  We can test all day long, but you folks always come up with new and interesting ways to stretch the product!  We triage your bug reports daily and welcome all the feedback you can give us.
