The size is not coming back. Anything else might or might not but the size is not and it's sad.
My only guess is - some kind of bespoke/niche phone maker with a good profit margin might make it "on demand". Of course not "one order from customer, one order to their factory" kinda setup - you get the drift. Some kind of blocking/reserving fee for priority shipping etc.
I had kind of hoped Nothing could be that OEM. But naah! Why would they! They literally are "yet another smaller OEM" in the crowd of other smaller OEMs with that gimmicky backlight as the only differentiator.
