ScottGu has blogged about the new features of the next version of Visual Studio (codename Orcas). Right now if you can get access to the bits (they're available through MSDN) you can start playing with it. I'm looking forward to see what kind of bult-in support they have for LINQ (released with .NET Framework v3.5).
The web (CSS, Multi-Target .NET Frameworks, JavaScript & Ajax) support sounds pretty cool too. I will make another post as soon as I get a chance to play with the bits.
