In 14 years, from the launch of the 1D-S Mark II, Canon's flagship full frame megapixels has gone up only 25 percent, from about 16mp to about 20mp with the 1DX2. Viewfinder frame rate increased from 4.5 fps to 14 fps. Total throughput (using framerate x megapixels) increased from 72mp/sec to 280mp/sec; about a factor of four over 14 years. That's an annual compound throughput increase rate of 10.2 percent.
Current throughput deficit: Sony A9 has 1.7 times the throughput; A7R3 has 1.5 times the throughput; Nikon D850 has 1.2 times; and the Nikon Z7 has 1.5 times.
The introduction of the R mount appears to have exacerbated this, siphoning off processor resources for various functions, giving the R camera 3.1 times worse throughput (assuming you want autofocus between shots for moving targets) than the Canon 1DX2. That means the Nikon Z7 has about 4.5 times the throughput of the R. The Nikon Z7 has 4 times the throughput, perhaps the most comparable camera to the Canon R in other areas.
This will matter to some people, and not matter to others. The Seattle DPReview crowd taking urban shots at their leisure will be less affected by that difference. The action/wildlife pros would be most affected. Interestingly, the latter is Canon's most loyal market right now, and the former appears to be their least loyal.
Something is going to change. My hope is that it's a big leap in throughput from Canon, and not a repositioning to less of an action profile. Including a poll to see if others are thinking about this.
