A few weeks ago I got a demo of the latest release of Urban Turtle - a SCRUM project management add on for TFS.  It is very nicely done.  Our Agile Project Management workbooks provide a nice SCRUM like planning tool but Urban Turtle takes it to the next level by making it even more visual and fit more seamlessly into a SCRUM regimen.  If you are doing SCRUM with TFS, I encourage you to have a look.  Here's their blog where you can learn about Urban Turtle: http://urbanturtle.com/blog/
