I have to echo the support for the 5D3 that many responses have elucidated. As a photography tool, the 5D3 appears to me the perfect response to what photographers asked for in response to the 5D2 shortcomings. As someone else has said, it's pretty nearly as perfect a DSLR as there is today, and it can effectively handle just about anything. It is the ideal camera for what I do. My nit is the price -- they priced it for people in business, and I'm not going to ever pay that price. I missed the Adorama sale last weekend, but it's apparent now the camera can be sold for $2750, and I'll buy one at that price. That will surely happen before the year is over.
So, I guess I disagree with the OP's premise. No camera company division leader would ever need to step down with a 5D3 on his resume. He's probably getting a big bonus. Now, this 6D, that's a different story; looks like a bonehead move to me. We all make mistakes.
