Visual Studio 2008 is anticipated out early next week, with availability for MSDN Subscribers. Check out the "Top Subscriber Downloads" area on http://msdn2.microsoft.com/subscriptions for VS 2008 downloads.
You will also be able to access these downloads by clicking on the Subscriber Downloads and Product Keys links that take you to all of your downloads.
According to Microsoft they will be using two different platforms to make these downloads available - to improve discoverability and reliability, and to balance demands on the systems.
As I've got to do some exhaustive business traveling next week's first half that'll give me some late night evenings in my hotel room to update all my Beta 2 stuff to RTM!
