Scott Guthrie has started creating posts about the upcoming features of VS 2010 and .NET 4.
I've never been a Microsoft fanboy, but you have to give it to them, they really seem to have listened to their users the last few years as they continue to change all the issues people have griped about. The first two posts indicate more good things to come - the web.config files have been cleaned up (at last!) and now it appears there are some great project templates coming. What I am really excited about though is the complete control of client IDs that's coming - the whole UniqueID/ClientID pain in the ass has always bothered me about ASP.NET, and it looks like that has finally been addressed in .NET 4. Flubba dubba.
