I have no real hopes in this. Love my iPhone 7, and ordered a new pixel for my android needs.I am afraid that "time will tell" -- but not what you are hoping for.
My reason? Cook is a bean-counter at heart.
I have a picture of him (maybe a farcical view) hunched over, reviewing each individual component of the iPhone and looking for ways to extract maximum profit by either down-grading or up-selling.
I guess I am looking into the predicted trickle down phones for 2018 with X features.
