One rumor would be that the Home button would integrate into the screen but not sure that's necessarily desirable.
I wouldn't say the 7 is minor over 6s, especially if the new SOC delivers 40% performance bump over the 6S.
Rumors had said they'd use the same design but that isn't the case. The camera bump is there but it's either the bump or a uniformly thicker device. With the OIS module, they probably can't avoid the bump without making the rest of the device thicker.
Also think the dual camera is the potential start of something big.
If iOS got an actual dark mode, OLED could very well improve battery life. It's why the Apple Watch has a dark UI for the most part.
