You're probably right about the direction Canon should go with sensors but that doesn't mean Canon will be right about it too. I find the rumour plausible for a couple of reasons. I suspect it's 32.5 total and 30 effective, giving about the same pixel pitch as the 20MP M4/3 sensors. Those perform competitively at a pixel level with Canon's current sensor. If Canon can match or even slightly better that pixel level performance then image level performance would be significantly better. They would of course need some diffraction reduction processing.
Canon already have a DPAF Mk II sensor in the works which has some ASTOUNDING abilities. It can eliminate Rolling Shutter Distortion and Flashband Effect, It can increase DR whilst reducing noise by splicing multiple exposures in a fraction of a second (called Multiple-Accumulation Shutter Technique). It has far, far less power consumption and yet a yields a higher Frame Rate. The patent number is US 9,565,381 B2 and it was lodged Feb 7, 2017.
The high-res EOS-R is expected to be about 75MP, which is also about the same pixel pitch. It would make some sense for them to design one wafer and cut it into those different slices.
The first R is a fairly solid camera but it's an incomplete one. The High Res model probably doesn't need to be 75MP but there will be a higher res model with 8K video since Canon have alluded to one in the works.
A third reason they might do it is to compete with the D500 as a sports/wildlife camera. They already have a reach advantage from crop factor. If they couple that with a 50% resolution advantage they can blow the D500 away for pixels on subject at distance. If they build a sensor for that purpose they're unlikely to build another one for the rest of the APS-C range, with shrinking sales.
We shall soon see.
We shall indeed. But it's baby-steps as usual. Don't expect to see too much too soon. I anticipate at least a couple of years before the EOS R reaches maturity. I also expect some of the design aspects to trickle down to the EOS M. There's two or possibly even 3 new M models on schedule for release later this year - if Nokishita (who have a 100% accuracy rating for leaks) is to be believed. Fortunately, my M6 is something of a fully featured APS-C model camera. The only reason to "upgrade" is if a newer model comes along that genuinely offers much, much more ability than current models.
