I'll post here what I posted on the f16.click site:
After reading this review it's certainly tempting to grab the X-Pro2.... but then again I bought my X-Pro1 for £699 with 2 lenses and the leather case, I've since sold the two lenses so the body & case only really cost me £350, I later picked up a grip from eBay for around £25, the 16mm 1.4, 23mm 1.4, & 35mm 1.4.
It looks like the Pro2 is retailing at £1,350 with used Pro1 bodies going for peanuts (£200-£250). Personally I also just picked up a mint full frame RX1R & EVF for £1,250....
I think most people would be far better served getting / keeping the Pro1 and investing the money instead in additional lenses, or something fun like say the RX1R, maybe an A7 + some legacy glass, etc. Hell get a 2nd hand Hasselblad XPan!
It doesn't mean I don't WANT one, just that at this price it really isn't worth it to me. Maybe if it was round the £800 mark I'd sell the Pro1 and make up the difference.
TL;DR : Too expensive, while I wish my Pro1 was the Pro2, I haven't missed any shots with the Pro1 to date.
