It's here. Imaging-Resource has an extensive preview posted. Let's all go see!
(A small voice in the wilderness: If this is like all other major camera introductions, you'll see a great deal of tearing of hair and rending of garments on the internet in the next couple of days. Let me just quietly assert something I've had to learn several times over in my years as a camera reviewer: you have to use it before you really know anything about it. You at least have to hold it before you really have a sense for what it's all about. So I'd advise trying to listen only to those who have actually held and used one, and to refrain from making great strident sententious proclamations yourself until you've held one. I can't always follow this advice myself, but I still think it's good advice. Cheers!)
