Apple's entire strategy this year and last year relies on display and camera differences. That same strategy will be used this year and next.
Basically, you're proposing Apple skip the iPhone X form factor and jump directly to discounting the iPhone 12 form factor. I don't see that happening at all.
Jump directly to discounting the iPhone 12 form factor? In what world is the fall of 2023 a jump?? It's 2.5 years from now.
Apple positions only one device per price bracket. They can put one device at $499. Why would Apple choose the iPhone mini, which has proven to be a weak seller, over the SE2 Plus?
The iPhone Mini will sell better when it's cheaper. That's pretty obvious. And the SE2 Plus? You want to throw hypothetical phones into the mix now? Come on mate.......
