Quad-Pixel is what I would believe, high Megapixel not. The R3 looks more like a Sport-Camera.
As I said.
This camera seems designed to be a 1D-lite with a lower price point, suspected higher MP and slower burst speed than a 1D/R1. This is how my brain is categorizing the R3 at present:
R6 is to R5 as R3 is to R1. Pure speculation, but possible.
There have to be numerous Canon buyers who cant afford or need a 1D but would look at something nicer than a R5/5D. This thinking proved sound regarding the RP and 6D/R6 series.
Anecdote: I shot with high megapixel 5DSr for several years (as a product shooter) and it helped me with my product photo business, but it often hurt my street photography. Given my shoot style and content, I would never go for a purely high-MP body again. I could easily be wrong, but a camera aimed at "photojournalists" sounds good for street photography, if the body size is favorable. So I could be talked into a camera that fits my street photo mentality. I respect high-MP, but the cons are too many for me.
Quad-P is likely, given the BSI, plus refined/faster AF and cooler operation.
High megapixel is very unlikely.
Given the problems with high-MP sensors, it makes sense to have the high-MP camera come dead last.
