I have read through all 56 of these pages today, and whilst I still have a love of Canon at heart, I can't see what would drive me to change back from Fuji. The new Canon body looks just like a DSLR, one of the prime reasons I moved to Fuji was the ability to use the knobs on the top plate to change settings rather than menus, and I just loved the retro looks.
One does have to ask, does FF on a mirrorless body make sense? Generally people shift to mirrorless to save weight & size, both of which are lost when you have to increase everything to take a FF sensor.
And by the way, I'm not a pro, but I wouldn't consider a new body that doesn't have dual slots, as I have had a card fail on me in the field.
