I doubt it... Fuji updates the X-Pro series slowly. It took 4 years last time.
this saddens me a little as during the Fuji X 1st gen, they marked the X-Pro as their top of the line product, unfortunately most photographers prefer the SLR style cameras and Fuji is catering to them by prioritizing the X-T series.
Anyhow, I just came back from The Camera Store as they had several Fuji X-T3 bodies and all lenses on the Fuji lineup to play with and am impressed with the AF improvement on the X-T3.
Shot the X-T2 and X-T3 with the same lenses (18-55, 56mm, 90mm, 200mm) and the X-T3 AF was definitely snappier, less hunting and more quiet. Eye AF was great too. Although I noticed that some frames were a little OOF.
If I were looking to go back to Fuji, I feel like X-T3 with 14mm, 23mm and 90mm would keep me happy.
EVF has once again been improved, I think the Leica SL still has the nicest EVF but the X-T3 to me is on par with the A7R3 or A9.
Sadly, talking with Billy from The Fuji Guys looks like Fuji still hasn't considered a View Mode function where the camera is always on EVF mode but Menu and Image Preview is accessed on the LCD screen ala DSLR.
