You can read all about them in the preview I wrote a couple of weeks ago: http://blogs.msdn.com/bharry/archive/2008/07/08/july-08-tfs-power-tool-preview.aspx
This is the first release of the Power Tools that we did some limited pre-release testing with our MVPs. It was very valuable because they helped find a few bugs that would have otherwise been in the release. The Team System Web Access update and the SCOM management pack are still in the works and should be available shortly. Also, for those of you looking for an eScrum update for TFS 2008, it’s getting close to being ready too.
Although it’s not as big a release as Dec or Mar, the feedback so far has been very positive. We’ve started development on the next set already. I hope to have them available in the Sept/Oct timeframe. I’m building one of them myself and I’m really psyched about it. I think you are really going to love this release. I’ll give you a preview some time in the next month or so. Until then, enjoy the latest release and let us know what you think!
