If your subscription is active I suggest downloading it. 2.0 to 4.0 is a major and GOOD jump. worth the bucks. They ahve added a whole section on Silverlight and MVVM.
Plus the MVC implementation is nice and updated for MVC2.
I just pulled down the update the other day.
Consider it a major improvement or UPDATE which it is.
It is current and fressh for todays development using VS 2010.
