What I hope they do is only release the iPhone “Edition” model. That’s it. Call it “iPhone” and available in black and 2 storage tiers: 128GB and 256GB. Be as ballsy as removing the headphone jack. The 7s and 7s+ glass-backed dummy models were only to catch leakers and throw off the public.
If they do something as stupid (not "ballsy") as that, and price the single model out of reach for even folks such as myself who can afford it, but are fiscally conservative, you will have a whole lot of people who are overdue for an upgrade jumping ship to the Android side.
I just had my 6 totally die, after terrible battery life since iOS 10.3, and I'm quite happy to "settle" for the regular 8 with a much improved 10nm A11 chip as well as a significant camera upgrade.
