OK so anyone reading this is most likely aware that Visual Studio 2008 beta 2 has been released but you may not be aware that today they have released Silverlight RC1, Silverlight 1.1 tools for VS 2008. Plus MS have released a refresh to Expression Blend.
Scott Hanselman's has the best post I have seen and is a one stop shop for all VS 2008 info.
