"Retro", as weird as the concept is, is about appearance, style, looks. It's not understood to be about function. If people want retro function, which most don't, it's a film camera. And those are widely available. I am not pushing for a "retro" digital camera because, as I have annoyingly said before, that isn't an elegant solution to anything, either appearance or function. You end up with something like this thing, a mashup. I can't even see how that "looks retro". It's a mess, stylistically. There is hardly a square centimeter they haven't stuck a freaking knob on in an effort to give every digital control it's own nubbin. I am sure it will be a nice digital crop sensor camera. Just because it doesn't look like a Z50, which is a more built for purpose design, that doesn't mean it's "retro".
If Nikon had wanted to do something retro enough to recall the elegance in industrial design they were good at in the past, they already had the blueprints in the vault. Could have been easily done, had it been more focused on actually being "retro". Leica, at least, seemed to understand what "retro" means when it released the M-D. That thing didn't make a lot of sense functionally,
because it's a digital camera, and forsook one of the larger advantages of digital cameras, the aptly named chimping, but, at least it was retro.
This thing below, that's what "retro" looks like if you are Nikon, and they could have, just as Leica did:

If Apple designed Nikon's retro digital camera. Clean, elegant, and to the point, even if it doesn't have a headphone jack any longer.
