The only thing I can see causing this are extremely high prices and a lack of innovation. I don't think the sensor stuff and DR stuff matters to the majority of DSLR users. I know quite a few pro-photographers and not one of them ever mentions dynamic range. It sounds like a lot of benchmarking tech geeks are on the message board. It reminds me of how people judge graphics cards by using 3DMark scores instead of actually using real games to judge their GPU. Even though I have a 5D3, in 2012 a camera should have built in wifi and usb 3.0 for $3500. I wonder how much these cameras actually cost to make and how much profit would they lose by adding little modern conveniences.
