Most interesting part for me:

"""For the functional programmers among you, it includes excellent F# support, powered by the same F# compiler used in Visual Studio."""

I've heard that F# is great from multiple people I trust a lot (and a quick cross check showed it does indeed look very cool) so I might give it a try once this is released.

I do some C# development (Unity Engine stuff) on my Powerbook so this is also good news (MonoDevelop is fine but I'll obviously test VS for Mac)
