I have an X-E2 and I love it, but I'm very curious to see if they release an X-E3 and what features of the X-T2 and X-Pro2 it will incorporate.
The whole X series is a pretty great system IMO. The designs are simple, bodies offer fully manual control, the lenses are extremely high quality, and certain models of lenses are much smaller than DSLR counterparts (18mm, 27mm, 35 f/2).
If you like classic manual cameras, especially rangefinder style ones, you'll like the X-E1/2 and the X-Pro1/2. The X-T2 however, is sort of an "SLR" format camera with the viewfinder in the center, which I'm not big on. One of the major advantages of mirrorless cameras (for me) is that you are able to put the viewfinder on the side and keep the camera's screen from smashing your nose when you shoot.
If you are into photography and haven't considered the Fujifilm offerings, I highly recommend that you do.
P.S. Fujifilm's engineers are continuously updating and refining the firmware from user feedback. With the 4.x release of the firmware for my X-E2, it add a boatload of features and really made it into the camera of my dreams. The 16MP sensor is getting a little bit dated, but that is going to happen with any camera. Plus, their X-Trans technology offers some advantages over traditional Bayer array sensors.
