Microsoft have just released the Visual Studio Roadmap details covering Whidbey and Orcas, you can find the article here

VB seems to be getting lots of fluffy features in Whidbey, Syntax/Semantic checking akin to the Word spell checker, and Edit-and continue which VB people have been screaming for.

Visual C# gets generics (templates) which will be fun, anonymous methods (need to look at this), and iterator improvements

Visual C++ gets Profile Guided Optimizations (POGO) which will be interesting, not that anyone seems to be doing C++ anymore :-)

Lots of good stuff in the Whidbey version of ASP.NET too
