Okay we will see you in a few years when prices are even higher.
Phones have reached a point where all future upgrades will be insignificant, at least for me (looking at the future roadmap for the next 3-5 years, in general - i do like OLED screen but it alone will never justify spending $1000 to replace a perfectly working phone).
What does iPhone Xs do, that a 6s does not? At least for me personally, nothing, which is why i will keep mine 7+ for a long time. Almost all of the Xs vs 6s new features are gimmicks and bragging rights (among those that care) - for those of us who use the device as a necessary tool the feature matrix has reached its peak, at least enough to justify not spending thousands of dollars ever year, or even every two years.
