We're told that Canon hasn't been fully satisfied with the sales of the Canon EOS 6D, a camera which I personally love for its size and simplicity. We're told that the next iteration of the camera is likely to move upmarket in features and pricing. As it sits, there's about a $1500 difference between the EOS 6D and the EOS 5D Mark III.
I think most people would rather see a $1499 full frame camera, but Canon seems to be marketing the EOS 7D Mark II on par with the 6D as far as image quality goes, so that might drive the 6D upwards, which in turn could also move the next EOS 5D body up as well. This is the opposite of where I saw things going, but increasing margins to offset decreasing sales numbers is good business.
