Eh, so does anyone really think these developer conferences are about what technologies people really use, or what is the most suitable technology or tool to solve [problem x]?
It is all about marketing the "next thing", and in many cases technologies that will never take off. Not about what people really use. That's why it is all WPF, Entity Framework, and WCF since a while back. And that's why Winforms, Linq-to-SQL, classic ADO, classic web services and other stuff that has a much larger user base is never mentioned anymore on conferences. Just browse through the PDC2008 agenda - shining example that the session topics are picked by marketing people and not technologists.
