I am using a 5 year old A7R and with the $400 additional rebates today I am ambivalent if I should still wait for A7R4 if announced next year 2020 with 60 megapixel or if delayed to 2021 with 100 megapixel...to be sure it will be priced closer to $4000...the A7R3 has sillent shutter, ibis 5 axis stabilization, higher sensor dxo marks and faster AF...but I continue to be happy with the A7R as a good partner to my Leica M10
any suggestions comments would help...to A7R3 or not?
Thanks
title should say or WAIT for A7R4
