I'm a film M user, have had bunch of digital Ms as well, and most recently had an M 262 for about 3 weeks. It had an issue and I was waiting for a replacement (was Certified Pre-owned). The store insisted that I could keep using it until whenever another one shows up, but none came up in time and I ended up returning it. I really liked it very much, but it's still a lot of money, and also I'm just never a fan of the whole size/shape/presence combination of digital M (IMHO!). I always grab my M4-P and feel "this is oh so perfect size." Anyways, I decided not to replace it with another one. I liked it very much, though.
Now, I also had X-Pro1 for a bit when it first came out. I've been an X-E1 user for a few years now including some work photoshoots with 2 bodies and the native XF lenses, which are really fantastic.
I just got the X-Pro2 a few days ago, and I must say I am really impressed. It's kind of amazing they could pull it off and release it as a consumer product as they did. It's hard to explain in words, but someone really loved that camera and went all the way with the concept of X-Pro line, and somehow convinced the high ranking Fuji execs to make the camera the way it is.
I currently don't have any XF lenses, and I'm just using the X-Pro2 with my M mount glasses using Fuji's adapter. This adapter is great with X-Pro2 because you can specify the focal length of the lens you are using, and the camera will bring up the closest matching frame lines in OVF. I know some people are not into that ERF, but I for one love it. I can really use the camera like I use film M when I want it to be (for my style of shooting YMMV), and it can still do pretty full-on modern day "digital camera stuff" when I need it, including using the native XF lenses. I know many people think the ISO dial is a bit too much, but I actually love it. I can really treat it like a film camera when I want to. And I'm so far very much liking the overall image quality (more of how it renders) of the new sensor/processor. I like the 1st gen sensor/processor like the X-E1 and X-Pro1, but I wan't into the 2nd gen one I tried on X-E2 and X-T1 for a few reasons.
I need to spend more time with it to really get to know it, but so far feeling pretty darn good. It's been a long while since I really fell in love with a digital camera, and I must say I am feeling it with X-Pro2, even just with my M lenses.
Just as a fun data, I bought a CLA'ed M4, a Summicron 35 8-element, an X-Pro2 and a brand new CV Ultron 28/2 for the cost of
Certified Pre-Owned M 262 back in April. Now you need almost another $1k on top of that if you wanna buy M 262 new today (CP in April vs new today as the Euro savings now gone). Now that's a lot of money!!
