Two of the most intriguing ones in my eyes are also adjacent in the session list:
Web Kit's Open Source Anniversary and WebObjects and Web 2.0. From what I've heard, almost nothing happened with WO last year, so any mention is notable now. And of course WebKit's interesting, because not only has it been a year and a bunch of committers have already been brought to WWDC on Apple's dime, but so much has happened with WebKit in the latest year.
