Typically, major announcements regarding new versions of the framework are announced at events like PDC. This year, it appears that they're not waiting and are starting to prime the pumps so to speak. Today they have posted a new MSDN site announcing VS 2010 and .Net 4.0 along with a bunch of videos on Channel 9. I typically don't do link posts (just LINQ posts), but wanted to keep them here for my own reference if not anyone else. Enjoy.
Visual Studio Team System 2010 Week on Channel 9! (20 videos coming this week)
I'm just as interested to see what is to come as you are. If you're in the Atlanta area next week, come on over to the Atlanta MS Pros meeting where we'll discuss how to cope while drinking from the fire hose that is the rate of technology churn that comes out of Microsoft at times.
