One of our relatively long term hosting partners - Praktik Hosting, has just updated their hosting offering based on our TFS 2010 product and licensing changes.  The result is a more affordable service with more features.  They are also going beyond just TFS and providing an option of licensing Urban Turtle for Scrum team management on top of TFS.  Definitely worth checking out.

I know of one more hosting partner with a near term announcement in the works and I'm hoping to be able to let you know about that within the next week or so.
