Sreenivas:
Thanks for asking. We are currently hard at work to getting the new Design Pattern Framework 4.0 released. There are many new items: Silverlight (MVVM, RIA Services), ASP.NET MVC (Testing, Mocking), Entity Framework, and there is a good chance that MEF (Managed Extensibility Framework) will be included (possibly using it for simple IOC in ASP.NET MVC).
Hope this helps.
