I am afraid there won't be an x-pro3. The x-pro series was the reason I bought into the Fuji system. A truly inventive and singular camera both 1 and 2 (as well as the 100's) With the advent of the XT's, H1 and GFX It seems the x-pro series recedes into the background. If Fuji does not continue with the x-pro cameras I won't continue with Fuji. P.S. I use the OVF 90% of the time.
IBS would be nice. They have it in the Sony 6500 which is no thicker than the x-pro
Nice to have a screen like the xt100 so that you could position the face into the body (no touch screen).but not necessary
3 magnifications to the OVf but more to the wide end for pancake 16mm or 14mm lens.*
A bigger and higher density EVF (Sony Unveils EVF with 1.6x Resolution Increase and 240fps Refresh Rate) Better eye relief and expanded diopter adjustment."
Always improved focus accuracy and speed.*
Complete program ability for all the buttons, especially the front wheel*
better battery life*
Keep up with sensor development as well as processor chips*
Simplify the menus and get rid of video function.*
We will see but I think this is all wishful thinking.
