More like, lenses that you thought were "very sharp" are not that sharp anymore, when used on a 36MP cam.
for this camera you need to remember that this is a 36.3MP file, so stuff that you were too small to see on a 12MP file now is visible
but because this is a 36.3MP file, now you can also see new details in your image that you could not see before
more details also means more sharpness
i believe that this is just the start and in a year or two, the other manufacturers will follow suit and 36.3MP will not look so huge anymore.
in technology, always look forward
but again i reserve judgement on IQ to after i have personally taken some shots with the camera
