Rumors are that while iPhone 7s/7s Plus are updates to the current generation, completely bezel-less with wireless charging and upgraded camera optics with support for AR/VR will be a separate model called iPhone 8 available to pre-order atleast after 2 months of announcement.
Fingers crossed.
Apple has a good ecosystem which keeps their users loyal. So as long they innovate on the software which is an important thing to consider when comparing Android ecosystem, Apple will be here to rule and compete.
