One of the reasons I love my X-E so much is that there's a lot of dedicated controls (not as much as on the X-T1/T2, but still), no need to go into menus for most adjustments. For this reason a universal touchscreen doesn't work for me, please keep the 4-way buttons adn the dedicated Exprosure Compensation dial. I want more dedicated controls not less - a joystick (as on the X-T2) would be great. Other than that:
- A dedicated ISO dial would be nice, but I could settle for index finger dial in the front for this (like on the X-T);
- The pop-up flash is actually surprisingly versatile and useful, it can be bounced off ceiling and can help when the subject is backlit, I do wish they kept it
- Don't make the controls a copy of X-Pro2. I like the layout of X-E better.
- The X-Trans III is a must, there's really no need for yet another body with the same old sensor in it
- Faster and more reliable autofocuss with subject tracking
- Tiltable screen
- Don't much care about WR. Hasn't been a problem, even though I mostly shoot outdoors.
- Larger and faster EVF but only if it doesn't come at expense of camera size or other abovementioned features. I can live with the same EVF, but I really want that new sensor.
- video features of X-T2
- a reasonable price
