sorry, but the guy is either crazy, or an ignoramous, or both and just wants your clicks. I happen to own two X-H1s and the new X-H2s, and there is not a single point where the new model isn't superior to its official predecessor. And regarding IQ: At least the high-ISO JPGs are definitely better. But Fuji never promised such and already said before their press-event on May 31 that regarding IQ there would only be minor improvements.
cheers, CF
