The point on the dual Digic setup I partially agree with you. Personally, I don't expect it to have one, like you mentioned, but for different reasons. In the past, Canon has used dual Digic setups in the 5DS and 5DSr, but I don't think it would be necessary in this application. I just don't see a need to increase the processing. Dual Digic would be an aid to oversampling 60+MP down to the various 8K and 4K resolutions, but that's it. 8K 60 is very likely possible on the current hardware (as on the R5C), if not for the overheating.

And that's the reason for dual processors. Power consumption would vary linearly with clock speed at the same voltage, but the need for increased voltage to get reliable operation at higher clock speed makes it more quadratic. So two digic processors doing the same work at half the clock speed each would only use about half the power, and would spread that power dissipation out over twice as much contact area.

Canon obviously hit the power dissipation wall with the R5, and only made incremental improvement in the R5c. The dual processor arrangement would make the most sense to get added computing power for and/or for 8k120 raw and/or down sampled 8k to allow focus breathing correction.
