I honestly think it is a 3dx. If I read the article correctly, the image was taken on an African Safari? Logic would dictate that shooting an animal in the wild a camera best suited for this would have high fps rate which the 5d is not known to have. If the 3d comes to the market (praying that it does) I would think that Canon would create the 3d as a digital still camera (no video, high fps) and a new 5d (video, slow fps). Since I am a mere mortal, no psychic powers, it is just fun to speculate on what is coming next.
