The Note series never went away -- I put four years on a Note 4 and am typing this on a Note 9, still in great condition. So I don't think it's really "circles" as much as Samsung deciding to have only one flagship model.

They removed the SD card slots and headphone jacks. They downsized the battery. They also lowered the screen resolution on the base models. I hate that we are getting worse hardware than previous years.
