I wonder what they would do with a higher end Fuji? It would seem like weatherproofing wouldn't be helpful, given the lack of it on the lenses. More mpx (based on 24mpx Sony sensor)? Maybe PDAF sensors for fast AF?
Oh, the other thing I would like to see on the lower end, is a built in flash. Kind of an ILC version of the X100, but maybe with the latest 16mpx sensor. I would actually vote for the traditional filtering, just to make PP/raw conversion a little easier. It would seem like that may be enough to keep the price point lower than the X-Pro1 anyway.
