It won’t interest me because of price but might incite a Z7 2 GAS attack if its price drops.
Have and like Z6 but so far have shunned Z7 because I prefer low noise of Z6.
No details yet, but quite a bit of information if you follow the trail of breadcrumbs. Large form factor (built-in vertical grip), like the D6. New stacked CMOS sensor. New processor. So I'm guessing $6500-8000 price, since these cameras seem to carry a price premium over otherwise similar DSLR models. So not something I would need or want. Does leave the door open for the Z8 to be an interesting upgrade from the Z7/Z7II, though. So far I'm still OK where I am with D850/D810/D500.
