On Nikon Rumors I found a link to an interview Imaging resource led with 3 Nikon engineers: https://www.imaging-resource.com/news/2018/08/28/nikon-z7-engineer-interview-deep-dive-q
It's lengthy and in some parts interesting while in other parts the engineers don't answer well - or can't answer because it's proprietary information.
The flange distance is the shortest of available systems. The diameter is very big because the engineers see f/0.95 only as "a step" but don't want to end there - meaning, wider apertures will come in the future.
As well as S-lenses will occasionally get low price colleagues and a cheaper body as well.
With FTZ adapter it's only PDAF measuring, no CDAF
The battery "grip" is also switching the display, so it's really only a stupid, additional battery compartment to screw under the camera - I guess it's meant for long time-lapses.
Not much to read about firmware versions and what will get fixed, or how they plan to update the camera in the future.
But one big deal - at least for me - is, thatwe read a lot about DLSR lenses are not meant to focus well in mirrorless cameras, something which was spread by a brand unnamed in the interview. The Nikon engineers say, DLSR lenses will focus as fast and reliable as they focus in DLSRs.
"Whatever the cause, it does seem that the Z7 loses a significant amount of its low-light AF ability when shooting with lenses slower than f/2. Whether this is a limitation of its PDAF system or an overall limitation of the Z7's hybrid AF system is unclear."
Takeaway for me: Good to have a lot of f/1.4 F-lenses, no high expectations about the telezooms (but for them I still keep DSLRs) and if Canon manages to bring dual pixel AF in their edition of a MILC, Nikon will only see dust in terms of sport or wildlife photography...
