I'm a little surprised that there is as much dissent in the Nikon camp. I guess they can always dial down the resolution on the camera, but overall it looks really solid. If I didn't already have so much glass that wasn't available in Nikon form, I'd seriously consider this camera.
How many people out there really need more than ~20 megapixels of resolution? I mean, unless you're making wall-sized prints, what's the use, especially given the file and pixel size trade-offs involved? We'll see what the reviewers think of the image quality when the street models hit, but I can't see much utility for most people in all these megapixels.
