But I for one, think this is too little too late. Is this enough to make us migrate of off Subversion, NUnit or CruiseControl.NET?  No but it might be able to fill a very small gap left by open source tools.  But I will not be switching from any open source frameworks for Team Foundation Server 2010.  We needed this about 5 years ago, why the U-Turn Microsoft? Probably because of the lack of Team System take up? Come on who do you know that uses MSUnit or Team Foundation Version Control (TFVC)?
