Yup.
Camera tech is improving but the only consumer-facing changes, really, will be in software like Google is doing.
Processing power is fine even in $200-300 phones now, it's RAM and type of flash storage that's more the bottleneck these days.
Battery tech isn't as dire as I believed, and power mitigation in chipsets is insane these days, but yeah, no big jumps there for a while (if ever.) Just steady progress.
Gimmicks have always been Samsung's bread and butter, they always like being first or close to it on things, but their track record on innovations is hit and miss. I'm glad the kinks are getting ironed out before the tech potentially makes its way to, say, the Pixel line.
