Since I haven't see much mention of it in this thread, I'll chime in that I find the usability of the XT-2 dials to be tremendously improved over the XT-1, and that matters a lot to me. With my XT-1, I frequently would take a photograph expecting to produce a single exposure only to discover that I am actually in exposure bracketing mode because I accidentally turned that dial when adjusting the ISO dial above it. That doesn't happen with the XT-2. The dials are nice and firm, and I haven't turned any without meaning to.
I'll also say that my first day at the dog park taking photos of running dogs with the XT-2 yielded more usable, in-focus images than all of my previous attempts to capture dogs in action with the XT-1.
