I am sure that Fuji could come up with a full-frame X-camera, but I would strongly advise them to first fix the issues of the existing cameras and then spend their resources on a new one. Too many X-100, X-Pro1 unhappy users out there, who are not throwing their cameras in the garbage, only because the love the images they produce. However, they hate the user interface, and that's something Fuji has to fix.
