Sensor is just one part of final image. DNR processor that recalculates image and deals with noise is the second most important thing.

Sorry, but without good data to process it's all futile.

Imagine that during 1/500s photo the machine will be able to capture 20 subframes, recalculate them, kill noise by repeated pattern control and use iterated subframes to gain "light" signal in shadow areas where needed and omit "light" signal in bright areas. Then even APS-C sensor might be able to provide something like 40mpix clean images with 25EV dynamic range on seemingly ISO25600 image.

A bit too overoptimistic, perhaps?

Computational techniques do improve the image quality - our Pentax cameras are already capable of Pixel Shift; however there are limits to consider. Your 20 subframes would be exposed for 1/10,000s - is there enough light for that?

Then, sometimes even 1/500s total exposure time isn't fast enough. Sorry, but this isn't going to make FF unnecessary

So guys, sensors are not the only critical part like they used to be in 2004-2012.. nowdays almost all sensors in current cameras have invariant ISO. If you push ISO100 image in PP, the result will be same as setting any ISO in camera.

Except for the likes of dual gain sensors.
