My X-Pro2 has signs of wear on the exposed edges and I am quite careful. I think it has to do with Fuji emmulating Leica Black paint M's. As you probably know, they "brass" as they wear from use. Fuji even had a simulated worn X-Pro on display at one time, if I recall correctly. Personally, I would prefer if they anondized the finished to make it less prone to paint wear.
That said, I plan to keep my X-Pro2 for a very long time. For me, the XP2 addressed the issues with earlier generations - 24MP sensor, much faster AF and the X Pro processor. I've just applied a lot of gaffers tape to protect the edges. After a few years, perhaps I'll remove it and let the wear and tear patina take hold.
