So the 7 will get 14-16nm? What will the A9 be, 18nm? Nm isn't a big deal coming from the S6 Edge to the 6+.
What I would like to see (if I were to get rid of my 6+, but on wait and see approach) would be more RAM, a significantly better camera (12 MP, capable of 4k perhaps), that killer S feature Apple does like Siri or Touch ID, expanded NFC use (even if I won't use it as much), multi-window, more exclusive iOS 9 features, expanded power management, LED notification indicator, force touch gestures, a tri-core or quad core processor, band 12 support, stylus built in, and a better front facing camera.
