If rumors are true, it’s likely we’ll finally see a high refresh rate screen in the base iPhone 17. Also, you’ll be able to compare it with the 17 slim/Air and see which one you prefer.
I’ve read somewhere else that this years iPhone 16 isn’t the beginning of a supercycle (although SoC+RAM wise, I do think it is), but rather next years iPhone 17 with a new design, taller display and who knows what other new feature.
Anyways, I think supercycles are mostly over, and the iPhone will experience small improvements and refinements every year.
