We still don't know how fast it operates and how quick the AF is. I didn't think the 50MP medium format sensor supported PDAF on sensor which means the Fuji GFX will be slow to focus in all but great light. I maybe wrong. This may be a new Sony 50MP Sony sensor that does support PDAF and it might have AF as fast as the X-T2. If the camera is fast it could give the 645z a run for its money. We will see how its priced.
Ricoh needs to update its 645 lenses with faster, modern AF motors and coatings. Some of them need to be redesigned for high resolution sensors. If Ricoh doesn't get busy and Fuji invests in the GFX system like it did the X-mount, then I could see Fuji passing Ricoh by in medium format market share.
