Well, it seems that man himself has spoken about details of this upcoming framework.  He has given us a timeline as well as what the framework encompasses.  What I find interesting is that it seems that Microsoft is not just building a "copy" of an open source project, replacing all of the Open Source libraries with their own, but actually building a framework that can interoperate with OpenSource libraries.

In other words, you are not limited to ObjectBuilder as an IoC container, you will be able to plug in Spring.Net, or Windsor, nor you are limited to MSTEST when it comes to unit testing.  I am truly surprised by these news from Microsoft.  Congratulations to Scott and his team.
