For me my r8 is matched (with my r7) for (travel/) backpacking.
I would prefer keeping the low weight/size and increasing the mpx. It would be great if they dropped the AA filter too. Maybe changing the battery to same as R7/R5ii, to reduce the camera bag weight.
IBIS is not a priority for me. I have the heavy IBIS R5ii, r7 already. The R6iii already has IBIS for others. IBIS would add weight and size. Most my travel lens have IS.
