I’d actually probably see the lineup without the standard 13 and 14 Plus, but keeping the 13 mini around.
So -
SE - 13 mini - 14 - 15/Plus/Pro/Max
I don’t really think it makes sense to have both the standard 13 and 14 since they’re very similar. And then the 14 Plus and 15 Plus together in the lineup. They’re still selling the 12, so that’s why I can see the 13 mini staying another year as long as they’re not replacing it with another mini.
