My 2 cents!
It's not just about sharpness and sharpening, but also about detail and resolution. A blurred edge in an image of 50 Mps could cover 6-8 pixels, on 21 Mps it might only cover 3 pixels, on 6 Mps it maybe only one pixel, or with positional luck, maybe even none at all, giving the impression of perfect sharpness, in-spite of low resolution and poor detail, hence the sharp images we were getting years ago from 4Mps sensors. (not breaking news, however, it is a contributing factor nonetheless).
The bottom line is, that, after being tested on the 5DSR, a lot of perfectly good lenses will find themselves, standing about trembling shamefully.......... with their pants around their ankles!
