Hi,Nikon's new mirrorless will most probably be one of the most advanced on the market from day one, and judging from history, ergonomics will be great.
- Nikon makes the most advanced full-frame DSLR on the market, the D850.
- Nikon makes the most advanced crop sensor DSLR on the market, the D500.
- Nikon made one of the most advanced mirrorless cameras for its time, although a commercial failure, the V3.
- Nikon is, as far as I know, still the second largest manufacturer of cameras with interchangeable lenses, after Canon and before Sony.
Any assumption that they won't include all their knowledge and all available technology in their new mirrorless camera is absurd. They'll do absolutely everything in their power to dominate this market, as they have done in the DSLR market together with Canon in the past.
I agree with you, but we can't deny that:
1. Nikon has the worst video AF. And they need to fix that to have an option.
2. Sony is way ahead at this moment. It's true that Nikon was the first manufacturer with sports class AF for mirrorless (the Nikon 1), but at the same time, Sony has the lenses and the expertise. They already made a bunch of errors, and learn to correct them. They also have the mind-share. Anything short of spectacular (in the price of features) will trigger negative comparisons. Remember: agreeing with people produces far more clicks. If it becomes trendy to joke at the new Nikon, everyone will do so.
3. Nikon does not have the resources to compete "1 on 1" with Sony. They need a barrier of entry, something that will force Sony to lost something great they have in order to match Nikon. If the big mount support a MF sensor that could be it, or it could be other stuff. Sony can't change the mount anytime soon.
Best regards,
