Jeez, Joe has been very busy on the VSTS front, and his blog is really showing it, he has some great articles, and for anyone who wants to stay in touch with VSTS as it moves through its early releases, I recommend you hook into Joe's feed. Good work Joe, and keep hobnobbing it with the rich and famous :)
On Joe's blog, he has a link to John Lawrence's blog, where I found this awesome article from eWeek. It discusses the support VSTS will have for other process frameworks, including MSF for CMMI, pronounced Kimmy (Look at moi CMMI, look at moi!), and MSF Extreme.
It's great to see that VSTS will ship with support for SEI and ISO processes as well as the MSF versions too.
