I predict both will use the large FF  'R',  and  'Z'  mounts, when they finally do surface, but I think there'll be a lot of models introduced before that.In some ways I think Canon has (will have) the edge in the APS-C Mirrorless arena with what will be the choice of two different sized mounts - the smaller 'EOS-M' for the entry level/value products, and the 'R' for the PRO level which would allow use of high end native 'R' mount lenses designed for FF, along with just enough of a sniff of DX wideangles to keep the punters interested. Obviously there is no upgrade path between the two sized mounts or interchangeability of lenses - but I reckon that will suit Canon just fine. I think they'd be more than happy to have their entry level EOS-M customers fork out for an entirely new R mount system (whether APS-C or FF).I think the big delay with PRO DX Mirrorless will be the AF performance.  For this reason I think CaNikon will also steer clear of going head to head with the Sony a9 (or likely soon a9m2 in time for the Olympics) with an 'R9' and 'Z9' offering respectively .... I think we're looking at least at 2021+ for those high speed FF Mirrorless models. Instead I think CaNikon will go into battle with the Sony a9m2 with their big gun DSLR flagships - the pending Canon 1DX MkIII and the Nikon D6.Perhaps sometime this year what we will see though are high resolution FF Mirrorless models of 60-75MP, likely called say the R8 and Z8 respectively. These may very well be replacements for the Canon 5DSR and the D850 respectively ..... perhaps we won't ever see those DSLR's upgraded again, or once more at most.I like the ergonomic size of the Canon 7D/ Nikon D500 when paired with longer telephotos, so I am seriously seriously hoping that we see a Canon 7D MkIII and Nikon D500S this year. The Mirrorless AF baby steps, and both companies seemingly having no plans anytime remotely soon to offer their long telephotos in native Mirrorless mounts, indicate to me that DSLR will be the way they will go with their PRO level APS-C offerings.The only caveat to this guesstimate is that the propeller heads and boffins in the backrooms may at this very point in time be nailing PRO APS-C Mirrorless performance, and be planning some surprise native Mirrorless long lens debuts - the 200-600 f5.6 in 'L' spec (as per the current 100-400 II), and the 600 f5.6 PF. If the body performance is a leap ahead of the current DSLR benchmark (the D500), and the ergonomics made sense, then I could get quite interested in that!  <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />  Otherwise I'd be very happy with either a 7D MkIII or D500S --- the thing that will tip it will be what 600mm Diffractive Optics come out to suit ......Either way I'm firmly waiting ......Chosun  :gh:</blockquote>
