Anyone who has read about when Steve came back to Apple, he wanted to simplify the Mac line, and drew a grid. Two options for for desktop, and two for laptop. One model of each was focused towards standard customers, and the other was the pro model. Just speculating, but what if this product grid was used for the 2019 iPhone lineup? Attached is a little mock up I made. But basically, you have a smaller iPhone XR, a follow up to the XR (forgive the name, I called it XR 2, which I know they won't do, but you get the idea). And a follow up to the XS and XS Max. What do you think?
