I get how mirrorless system cameras have been overtaking DSLRs for a while now, but are pros moving away from DSLRs too? Every time I see a pro photographer (news, wedding, sports, etc) it looks like they're still using DSLRs. It's probably just my bias, but I can't imagine using an electronic viewfinder to the complete exclusion of an optical one.

Although, with so little change in cameras from year to year, it makes sense that this would be Canon's last EOS-1D, as long as they keep producing it for a while.
