looks like Fuji nailed it this time !preorder yours from Adorama!
Vastly improved AF speed, choice of shutter speed limit in auto ISO mode, focus peaking and split screen for manual focusing, improved viewfinder glass to resist finger prints and less distortions, focus selector switch on left panel, change focus points with the right hand only and of course the new 16mp Trans X sensor-
makes my analog blood boil
