Today Microsoft has made available Expression Blend 2 for MSDN subscribers. It's just a bit difficult to find. :-) For those who want it, log into your MSDN subscription.

Expression Web 2 MSDN Download

As you see the first Service Pack for Visual Studio 2008 has been releases. Be aware it is a BETA release and it currently BREAKS Silverlight 2 tooling (which is in beta, too).
