Conchango decided to go ahead and release the beta for the 2.0 release of their TFS Scrum Project Template. This version works with TFS 2008 and has many new features. Unfortunately my first attempt to install it failed, but I think it because I tried it on the TFS 2008 CTP virtual PC image.
The beta for the MSBuild Sidekick 2.0 has also been released. It has many more visual tools to help you create custom builds scripts.
Hopefully I will more info on these as I use them over the next few weeks.
