Well, I'll definitely get the Z fc and the 28mm SE (not because it "SE", but because it's a small 28mm). Pending the quality and availability of the additional grip, I may even trade in the Z 50, though I doubt it - the Z 50 handles fantastically with big lenses, and I have yet to find any additional grip that gets you the same level of comfort and peace of mind.
Classic styling, slick *and* light, full dial control (to a point - no aperture ring on the lenses; Fujifilm still wins there); articulating screen, "chimp prevention" as well as protection for me, but also more versatile for low-angle shooting, like I enjoy on the E-M5 III; USB-C charging - and it stays fully operational while charging, which opens up opportunities and might turn this camera into an even more desirable travel option than the already impressive Z 50; even a slightly enhanced handling paradigm as well - no more on-screen soft buttons you can bump with your nose (I really don't like those on the Z 50). For me, apart from the styling, this is actually a Z 50 on a reasonable amount of steroids, though minus the seamless ability to use bigger lenses (so it's *not* a camera I would use as the kind of free tele-converter I got with the Z 50).
The 28mm is exactly the right size and has a great minimal focus distance - for me, that lens is a serious no-brainer; I still kind of wish they had released the "normal" version (and the 40mm f/2) at the same time because I would like to have the option to go for that, but I don't mind a bit of bling in this case - it *does* look good with the classic focus ring and metal-like ring, even though both are gimmicks, and I don't think I'll be bothered by that style on the Z 6.
All in all, that's exactly the move Nikon needed; besides, as has already been speculated, the fact that this is called "fc" opens up the option of an "f" in the future that might only be slightly bigger, but that again opens up more opportunities for more features (think about a body like this with I.B.I.S. ... - it should be doable, considering what Fuji and Sony have done recently).
I'm happy with what we get at this time - including pricing
