If you're thinking of heading down to Orlando June 3-6, 2008 - you can check out the list of sessions which has been recently posted here.
You also have the option of rating sessions that you might be interested in. I assume this is to help plan room sizes.
I'll be doing a breakout session called "Building Next Generation Data Access Layers with the ADO.NET Entity Framework" in the Architecture Track. I'm really looking forward to it. Hope to see you there.
