Well, if Apple can fit the iPhone 7+ into an iPhone 7 form factor, then there is no reason to have 2 form factors any more. We would have the best of both worlds - screen size and portability.Everyone is talking about the prices this year but not for the next.
What happens next year? If there isn't another release like 7s/7s+ next year and there is just the 5.8" and perhaps a 6.5", where does the pricing go?
Maybe with enough scale, we can see the price of next year's iPhone drop by $150-200? What are the odds of this happening?
