Well Microsoft’s DreamSpark now has Expression Studio 2 for free. Remember that DreamSpark is free software for students like Visual Studio 2008, Windows server 2003, and Xna Game Studio 2 with XNA Creators Club 12-Month Student Trial Subscription. They still list Expression Studio 1 but if you click for the download you will get an .exe file that is version 2 (version 1 was an .iso file). channel8 needs to update their site, look like they had version 2 since May from its user forums.
