Jason Zander, Visual Studio GM posted a couple of tutorials about the new version (beta).
You can download the beta from here, get instructions on how to download it from Channel9, and then go to Zander’s blog and play with the tutorials.
Big news: modeling tools, improved efficiency throughout the test cycle, better collaboration capabilities, and the new .NET Framework 4.0
If your school has MSDN AA you can get it from there too.
