The replacement for the Canon EOS 5D Mark III is going to have some very big shoes to fill and cannot be an incremental improvement of the affordable workhorse of the Canon lineup. The EOS 5D Mark IV has to be a revolutionary upgrade in performance, or people may start looking elsewhere for a camera body solution. I do believe the entire market is waiting to see what Canon does with the EOS 5D Mark IV.
This is the kind of BS that non techno-geeks hate. Unless, of course, you are working for Sony or Nikon. There has never been a revolutionary upgrade in performance of any DSLR. All the upgrades have been incremental. Basic physics has told us this for years. If Canon continues to make extremely reliable and high-quality cameras, then there is no reason not to buy the 5D mark IV. I fell for all the techno-geek talk about the Sony A7's - how far ahead of Canon Sony has risen. Unless, of course, you take normal photos under normal conditions where the extra DR is not even noticeable. I wanted to replace my 6D with the A7 II, but the Canon was better in pretty much all aspects that I cared about.
Yes, people will start looking elsewhere if sites like this continue to perpetuate the techno-geek attitude that all that matters is test results and lots of bells and whistles that end up not mattering when you actually take photos. Yes, 9 fps must be so much better than 8 fps although in real life it will never make a difference. 28 MP must be so much better than 24 MP although no one would ever notice the difference. 14 stops of DR are so much better than 12 stops although it real life shooting you'll never notice the difference.
I have no loyalty to Canon. My first 35mm camera was an Olympus OM-1 - so that is the only camera company that I have a soft spot for. When I have bought cameras in the past (as recently as 2 years ago) I compared brands and bought the camera that I thought had the best IQ, as well as the one I thought had the most consistent and reliable exposures. When I buy my next camera those will be the most important criteria, too. It is highly unlikely that Canon will need to be "revolutionary" or make major changes in order to compete.
But Canon will continue to lose customers as long as the techno-geeks are driving the conversation. I'm sure they are thinking that they are trying to save Canon by forcing changes. Instead they are driving people away.
