Nothing is still able to replace my nx1 as an all around still+video camera with great quality, 24-200 range, fast native af lenses. Fuji is near, but still not there. M43 for me is a no-go for the ratio in stills, that I never liked, the low mp and smaller sensor.
A7r-iii is there, actually would be my best choice, but definitely too expensive, especially with decent native lenses.
Nikon could do something good, but I bet it won't.
