Buck Hodges just announced two Visual Studio Team System discussions, scheduled for the afternoon and evening of December 5th (http://blogs.msdn.com/buckh/archive/2007/11/28/visual-studio-team-system-chat-december-5-2007.aspx.)
I don't know how in-depth the discussions will be, since the intent is to cover everything from Team Foundation Server to the various editions of Visual Studio to new functionalities such as Continuous Integration support - but it is a chance to interact with the key people involved in making our lives easier on a release-by-release basis, so I will be there for one or both.
The times are 1-2pm Eastern and 7-8pm Eastern. You can add the appointment to your schedule by visiting Buck's blog entry.
Buck noted in his blog that he intends to take part in the first chat, in case anyone wanted to know.
