R6II apparently allows the choice of 40, 20, 5 and 1 fps in e-shutter. Why they left out 10 baffles me. IMO it would be what I'd probably leave it at for most situations other than fast sports action and when I have the luxury of being able to work with the increased number of files generated at 20 or 40 fps.
My main question is if the R5II is ~60MP, what will Canon release to fill the substantial 'intermediate' range resolution gap of ~FF36-45MP?
Will it be an R5 refresh in another guise? Something more innovative? A pro-level speed demon to compete more directly with the Z9 and a1? Canon could keep selling the current R5 at somewhat of a discount, though this hasn't really happened with the R6, yet, and isn't something they've done before with their higher-end cameras, that I can recall.

But if I'm going to upgrade, an improvement in rolling shutter would be nice. Not sure the kid is going to keep playing much longer, so some MP and further low light performance may be handy for other general use. But it would still be nice to have something as sports capable as the R6.
I'd thought of saving up for a R1, but I'm no sure what it would really bring (time will tell), over something like this, besides the BSI sensor. I'm sure it will have a ton of features, but whether they are practically useful for me will remain to be seen, as well as the cost. R3 Would do it too, but at 3x the cost of the R6 and similar resolution, I'm not feeling it at it's current price. The next camera may be my last, so I'm doing a lot of thinking about what's what.

Well, the 24MP sensor in the R6II isn't BSI and apparently has improved rolling shutter vs. the R6, so it's probably relevant to the speed of the sensor and its components and not entirely its architecture. BSI is supposed to improve light collection efficiency for a given pixel size by moving non light sensing components out of the pixel well to behind/under it. Stacked sensors improve readout speed by moving related components closer to the pixels for faster processing. So far other than the R3, Canon found ways to adapt FSI and remain competitive... Consider that the R5's FSI sensor is higher resolution than the R6's and has slightly better rolling shutter performance. Given the pixel density of the R7's FSI sensor is approximately equivalent to 80MP on FF, it's conceivable Canon might continue to use FSI architecture for a while still if it remains competitive with BSI offerings. If you look at the Sony a7RIV and V, those both have horrible rolling shutter performance. But the stacked BSI sensor in the a1 (and also the one in the Z9) is much better in this regard.
So I don't think BSI is guaranteed, though it's possible Canon will develop something BSI-like that functions similarly.

And why would the ARM processors not have better performance 3 years later? It all seems like a wish list, but nothing would surprise anymore. There is no legal or financial accountablity for the rumour accuracy.
