This is what appears on the Canon teaser about the upcoming Canon EOS 5D MkII. As we can see, Canon made sure that several important zones are hidden (the yellow-ish parts at the bottom, at the top of the lens, under the EOS marking). But we can see that the design is much smoother than the previous EOS 5D. Obviously the same organisation, too (from the button outlines) and no integrated flash at the top.
Not enough to anticipate the 17th September announcement.
