DxO will not process mRAW & sRAW files. According to their support, it's because those formats miss some information the software requires.

Don't you think Canon is able to add crop or s-raw modes that reduce the data rate before the bottlenecks?
With the (imho) inevitable trend towards higher resolution there has to be some basic/new research done in this direction ... Canon would probably like it but they cannot expect all people to buy two camera bodies, one high-res, one high-fps. You could counter this trend by introducing faster cpu cores and interfaces, but the question is if the current embedded tech is developing fast enough.

Why not? For years, we had the 1D and the 1Ds lines. The 1D X price at launch was between the 1DIV an the 1DsIII launch prices. If they do have one body with both high-res and high fps, what will they charge for it? Likely well over $10K, and I doubt Canon will leave that large a gap between the 5-series and the 1-series.

75+ megapixels. What's the point? There are plenty of 35mm cameras available that can deliver the file sizes and resolution needed for every application imaginable. Then add some interpolating software... And zillions of pixels in a 35mm frame will never be better than less pixels in a medium format sensor. There are several reasons why photographers choose to shoot medium format over 35mm and it's not just pixel count. ! Having said that, Canon probably realises that there are enough people out there who will keep on buying cameras with the most pixels just because they can rather than whether they need them or not.
That's why they do such great business.

That would be one sure way of making multitudes desire one, crave one, the holy Grail of EOS.
And they'll be left with the reality of having to frame properly and only enlarge pics to the size of a truck with their paltry 22 mp.

You would never really be able to "unbin", as the pixel halves are each under a single microlens and color filter. There wouldn't really be any point, since you would have two halves of gree, two halves of red, two halves of blue. That would create a real oddity for digital interpolation, assuming you could get any benefit at all.
The term MegaPixel usually refers to output image pixels, not photodiode count. Keep in mind, there are usually more real "pixels" in a sensor than can be counted from the output image anyways, and have been for some time. For example, an 18mp sensor usually has nearly 20mp actual pixels. It just doesn't seem logical for Canon to start counting their half pixels used for AF...
By my calculations, a 75mp FF sensor would be 10600x7050 pixels in size, with 3.4 micron pixels. That is actually not all that bad. That is similar to a 24mp APS-C sensor in size (which is very interesting...would make sense if Canon has already produced a prototype 24mp 7D II sensor.)
I really don't see how Canon could keep using a 500nm FSI sensor design with 3.4 micron pixels. Given they have a patent for a BSI design for APS-C and FF, I wonder if these two sensors are using the same architecture.

Do not use DXO then.
BTW, if they want to survive, they would have to support mRAW and sRAW.

As far as 16-bits....now that is something I could not care less about. Because 16 bits will not give you more DR. Just bigger files with the extra bits quantizing noise.
14 bits will do just fine.
A pixel produces an analog signal that is relative to the amount of light it has been exposed to. That analog signal is sampled by a D/A converter and becomes a digital number. The number of bits of resolution of the D/A converter is the upper limit of the DR of the camera. If you have a 12 bit D/A, the best dynamic range possible under ideal conditions is 12 stops. If you want 16 stops, you need 16 bit D/A and that means 16 bit RAW files.
Dynamic range of a pixel is not the same as DR of an image. When the pixel count increases, the number of bits can drop without a loss. If 16 bits "were needed" now (many would argue that with the high read noise, they were NOT), 14 bit would be enough with the new sensor. With a "zillion" mp sensor, 1 bit would be sufficient.

A. You're missing my point.
B. If someone gifted me a 75MP camera tomorrow morning, I would paint it blue and throw it into the sea.
