I was surprised after seen the first rumors. It's a different decision than Canon's multi mounts, being the small APS-C ones with no sufficient lens choice and relying on adapters.
But it's only 1/4 of the price of a Z 7 which in DX-mode roughy has the same MP, same number of focuspoints. It's rather compact with this ridiculously slow 16-50 expandable cookie-lens (for pancake it's already too fat).
As most, if not all (design)decisions of the Z line are made more likely by clerks after investigating the most riskfree design solution and then cheapen the shit out of it, good for all potential buyers/users, but no excellent use for any of us (see the contribution to plastic waste called MB-N10 BATTERY
PACK (therefore at least not mis-named "grip")) I'm very tempted to look elsewhere for a more modern camera. With better features, ergonomics, IQ - but I have to say, so far I can't see one

.
Sony needs being a bachelor of of arts for understanding weird UIs, but has the best AF - so it might be worth to take the trouble and learn complicated menus?
Canon needs tolerance for mediocre sensor design.
Panasonic could become a choice, after Sigma releases their L-mount line, and improving the AF-C
Fuji is nothing I like to use as much as the Z 7
Pentax still cheers about "innovations" that happened in other time bubbles five years ago and has nothing to offer in mirrorless
