It's interesting to see both Nikon and Canon introduce pro-level cameras with modest increases in megapixels compared to their previous iterations. Of course, both of these cameras are aimed at the photojournalist and sports photographer, where operating speed and low light capability are most important. My assumption is that they are concentrating on real image quality, higher dynamic range, and less noise than just resolution numbers, and if so, this is a good direction. My older 10 MP DSLR still makes great images, so there's no reason they can't do better with the latest sensor technology. The D4, like the 1D X, probably won't be seen in the metal till late this year or early next year. So don't hold your breath.
