I ended up ordering on Wednesday night, I'm trading in my Z Flip 5. While the Flip series has been fun to own, I'm tired of the soft screen and the rather narrow width of the screen, not to mention the lesser cameras. Since I haven't had an S-series since around the S21, it won't bother me with how small the updates are from the S24.
As for the lack of updates, it is something we need to get used to -- cell phones have matured to the point that there aren't a lot of major upgrades year to year, instead it is now mostly limited to slightly faster processors and software improvements, with maybe an improved camera.
