It's a very good deal actually. The X-Pro2 is my personal favourite Fuji camera. I've used the X-Pro3 for a couple of days but decided not to switch for a few reasons. First, there's no visible improvement in image quality. The new sensor/processor are mainly an improvement in continuous AF whereas I mostly use single AF for my personal work with the X-Pro2.
Secondly, the OVF is a bit brighter and larger on the X-Pro3, but it lacks the dual magnification of the X-Pro2. Therefore, you can't actually use the OVF with lenses shorter than 23mm or longer than 50mm. The EVF of the X-Pro3 is better though with its 3.69mp vs. the 2.36mp of the X-Pro2. However, one of the reasons to use an X-Pro is the OVF capabilities.
Finally, the LCD is only nice for waist level shooting, but otherwise a pain in the a*s. To use the menu you either have to flip down the LCD or use the EVF/OVF in combination with the joystick. When wearing glasses and left-eye dominant (like me) this is useless as you're constantly make stains on your own glasses. I'd rather have an X-Pro with the articulating LCD of the X100V. The sub screen on the back is just a gimmick. Because it lacks backlighting, it becomes useless in less than perfect light.
