First shots on my Pro-2 this morning, and it's a wonderfully handling camera - I immediately like it even better than my X-T1 (itself a beautiful handler), although the EVF is not quite as good. The joystick makes a big difference, and the shutter speed, exposure compensation and control dials are all improved. I even like the dial-in-dial ISO mechanism better than the locked dial on the opposite side of the X-T1. I really don't miss the drive dial, which I knock out of position frequently on the X-T1 (I use it just enough that I can't always leave it shut off - I'd far rather have a drive mode button in X-Pro 2 style). Build quality is improved from the already very good X-T1 (the most noticeable spots for me are the dials and the SD card door).
Who knows if all those improvements will make it to the X-T2? I suspect a couple of them will, but others won't. I'd be surprised to get the big, beautiful shutter speed and exposure compensation dials, because there may not be room on the X-T2's smaller top plate (unless they make the body a bit thicker). Since the tilt screen takes up additional space, I'm not at all sure the joystick will fit, either. On the other hand, there will be some improvements that go only to the X-T2... X-T2 owners WILL get a tilt screen, and I have a strong suspicion it might be a touchscreen if the joystick doesn't make it. I'd be very surprised if some version of the improved card door design doesn't make the transition to the X-T2, and I suspect the front and rear control dials will either make it or even see another improvement. There is, of course, more room for an EVF in an X-T2, so it will certainly have the higher magnification from the X-T1, and possibly a higher resolution or refresh rate as well.
One real determinant of how advanced the X-T2 will be is where Fuji decides to position it in their line. With some of the new lenses (especially the long telephotos), it might make sense to have a body above the present position of the X-T1 ($2000?). Such a camera would have a very high frame rate, dual card slots (maybe both UHS-II), and a really high grade EVF similar to the one in the Leica SL. It would probably also have very high grade video - 4K with a high quality codec and high bit rates. It could be a true hybrid camera, similar to an A7rII in that respect, although without the full frame and very high resolution, and with the full Fujinon lens lineup (not a "mostly video" camera like an A7s or GH4).Both the sensor and processor from the X-Pro 2 can actually support a hybrid like that. It might be a slightly larger or heavier body to accommodate even better weather sealing, some of the X-Pro 2 controls and more battery capacity(although a grip might be a nice approach to the battery issue, rather than an inherently larger body). If they did this, I would hope they leave the X-T10 in the line and introduce an intermediate model with the new sensor, but without some of the bells and whistles.
The other option would be a camera positioned similarly to the X-T1, rather than above it. It has already been confirmed to have 4K, but I wouldn't expect a fancy codec at X-T1 positioning. Similarly, the viewfinder will probably be very, very good, but still a 2.36 megapixel unit, not the much higher resolution finder from the very expensive Leica. Body size will almost certainly be nearly identical to the X-T1, meaning that the enlarged shutter speed and exposure compensation dials from the X-Pro 2 probably don't both fit, although one or the other might. I hope they manage to include the joystick, but, looking at the back of my X-T1, I'm not completely sure where it would go?
