No mention here yet, but many here have already dabbled in some mirrorless offerings especially with Sony's APS-C and full-frame bodies...plus the occasional micro-4:3 or Fuji APS-C user. But the mirrorless market is expanding exponentially now, as Sony's development and lots of media attention and reviews seems to have officially spurred the competition to jump in forcefully. Nikon Z full frame mirrorless debuted. Canon EOS-R full frame mirrorless has debuted. Rumors point to an upcoming Panasonic full-frame mirrorless to come. Sony continues to develop and expand its full-frame mirrorless system, and rumors of a new APS-C super-body to come soon. Fuji continues to update their APS-C mirrorless with a new fortified X-T3 on the way. It's starting to look like the very beginning of a turning point...like when 35mm format won out over others, when SLR took over from Twin-lens and rangefinder to become the dominant format, when AF popped up in SLRs and everyone followed quickly...or even when digital SLRs kicked in fully to end the film era. Now, are traditional DSLRs seeing the first notices that future development dollars will go into mirrorless bodies and lenses, especially given both Nikon and Canon have debuted brand-new lens mounts for their full-frame cameras? Nikon now has to consider lenses for APS-C and full-frame DSLRs, and now Z...Canon even more spread out has to consider supporting APS-C and full frame EF lines, PLUS their M Aps-C mirrorless line, and now their R full-frame mirrorless line. Nikon and Canon are still in the early phases with their full-frame bodies, both still falling short of the capabilities, speeds, and lens collections of their DSLR systems, and several generations behind Sony's mirrorless - but they certainly are showing that they've been studying the competition and there's a lot of imitation and copying, and a rapid development and improvement for next-gen bodies seems likely for both. The main question is: do Nikon and Canon debut new-and-improved full-frame DSLR pro-bodies at the same time as the mirrorless full-frame bodies? Or do they slow down on DSLR to concentrate on mirrorless, letting the increasing development of the mirrorless bodies get all the R&D and existing DSLR users continue to keep the bodies they have, or consider adapters to start the transition to the new systems? The future will be interesting indeed.
