I'm interested in this lens for my XPro-2. I don't *always* use the optical viewfinder but have long wanted to have a 23 that wouldn't block the lower left 1/3. The 23 f2 never seemed like a good option to me because so much corner performance was "cooked" into the RAW files by Fuji. And I already owned the old 23mm f1.4 (love that clutch.)
I will probably pick up a kit and sell the body after a few more reviews cover color and other "softer rendering benefits."
