Sony A7R, which in all likelihood will still have better DR, probably also better noise performance if the new Canon sports >40+ Megapixels.
how do you know... the camera is not even announced.
what are the parameters for your likelihood calculations?
is there a natural law that canon has to stay with the 500nm process and will not improve analog digital conversion etc?
my guess is..... at some point canon will have to do the jump to a new manufacturing process.
and for 40+ MP i guess canon HAS to do it.
there is a reason canon sticked to 22 MP.
imho it makes no real sense to increase pixel count to 40+ MP and stay with the current technology.
so i know as much as you do..
but i think it´s more likely that canon will close the gap or even trump sonys sensors.
