I notice a pattern with the 5DIII and 6D:
Canon introduces the camera, the internets light up with complaints (too expensive, not enough improvement, features "crippled" etc. etc.)
Then the camera finally hits the users' hands and within about three months the complaints start to melt away as real users get hands on experience.
Turns out the only legitimate complaint about the 5DIII seems to have been the cost. But, the market is fixing that.
It now appears that 6D users are pleasantly surprised at how good this camera is for the price and how close it is to the 5DIII in the area that counts (the quality of the images).
As someone who is anxiously waiting to see what they do with the 7DII, I'm now expecting two things to happen. First, whatever Canon produces will cause all sorts of trolling on the internets from the usual suspects and, Second, once the 7DII is out for a few months, real users will be impressed with what a solid performer it turns out to be.
