After a few weeks of contemplation, I have decided to replace my X-T20 with the new X-E3 as my travel system camera. While I miss the tilting screen of the T20, I prefer the speed and convenience of the E3's focus stick. All things considered, I'm faster with it, and I'm used to working with it from my X-Pro2, X-T2, X100F and GFX 50S. Unlike the tilt screen, the stick it something I use with pretty much every shot, so I benefit from it all the time.
I also like the superior firmware of the E3, because it includes all those improvements from the two recent X-T2 firmware updates, such as an AF ALL mode, a super-small AF frame, putting ISO on a command dial, up to 15 minutes of T exposure time, separate Shutter-AE/AF settings for AF-S and AF-C, etc. etc.
Finally, there are the color histogram with live overexposure warning blinkies that I use all the time in my GFX, and the much faster/better AF tracking algo (which will only come to the T2 in November and who knows when to the T20). Price is identical with the X-T20, so the E3 it is.
