- Expeed7 (8 as 7 is old by now)
Not a chance. Expeed7 is basically state of the art, and has IP in it that other camera SoC's don't.
- Button layout like a D750 with a joystick
Sorry, but Z System cameras are all headed towards the same basic UX. If you're unhappy with Z6 II/Z8 (which are slightly different), you're not going to get what you want. No way Nikon changes controls back.
- Warm LED lamp af assist (with constant feature for video)
Sorry, but Nikon/Sony AF is done on blue/green rows, so a red AF Assist lamp just isn't seen.
- Dual micro USB-II with an internal SSD buffer
- ~50 frame RAW image burst
Ugh. Micro USB? Nope, Europe says it won't happen. Do you mean UHS-II? Also seems unlikely. SD is now a transition storage format. CFe is the future, and Nikon is already there.
EXPEED7 puts a 20 fps limit on RAW. Thus, your wish here is solely determined on image sensor offload speed (or an arbitrary governor that Nikon applies).
- Entirely new approach to AF
If you mean the Z8/Z9 approach, that's a given, though on lower cameras we might get subsets.
- Entirely new approach to menus/settings
- swap i menu for 12 recall all settings
- mark settings global/locked
Not going to happen. Nikon's highly reluctant to change things that have been "legacy" for so long. Will Nikon tweak some things with menus/settings? I sure hope so, as the Z8/Z9 menus sprawled in ways they shouldn't have, and the linking of stills/video banks/U# is an ongoing issue for cameras that say they are hybrid.
None of this is all that revolutionary in this market. All existing technology.
Absolutely.
