Good question. I have wondered the same thing. I have an X-Pro2 and was considering the X-Pro3 until I read the specs. I am waiting to see what the X-Pro4 looks like.
A lot of my reasoning is simply that I really like the camera I have and I would only make the jump to a newer model if it offered some feature or function that I really wanted. I use the display on my current camera quite a bit - just to check battery status or show a photo to someone. I don't like the way the display on the X-Pro3 was done. I really hope Fuji goes back to something else.
Very nice photos. I have thought about getting the Fuji 80mm, but have been dissuaded by the weight of the lens. After seeing your examples, I might have to rethink that. Thanks.
