Looking at the "maybe" specs for this camera, have they fixed the rolling shutter issue you think? I want to get the R6 III and R7II and shoot just electric shutter, currently with my r7 for sports with bats and ball I shoot EFC because of rolling shutter. If the R7 mark II is rumored to have E-shutter only, I am assuming it's fixed. For the r6 mark iii not sure why you would release it with a rolling shutter issue.
