I hope the hell not.
Remember the A7r ? Shutter shock, jello EVF, EVF blackout and lag, 11+7 bit compression, crap battery life, abysmal weather sealing and depreciation faster than most English cars.
Hopefully you got this one right Nikon. We will be waiting on the sidelines to see what faults are cooked in and what faults were avoided. I can still take photos today and tomorrow with a D850 so no hurry here.
