Is it really surprising that the next iPhone 7 will be similar in design to the 6/6s models? This is simply following Apple's historical design language for iPhones. iPhone (original) & iPhone 3G/3Gs - very similar design language used here between all the models. Apple hadn't thought of the S cycle with the first phone so this is three handsets that all are basically the same design albeit the smaller details. Similar button design, shape and feel (except the aluminium vs plastic body) iPhone 4/4s & iPhone 5/5s (& SE) - again similar design language used here, volume buttons, flat slab shape, antenna design etc. The only change here was Apple being forced to move the screen size from 3.5 to 4 inches with the 5 in an attempt to appease the large phone brigade. If that wasn't on the cards the 5 would have been very similar to the 4....the aluminium body was a result of manufacturing efficiencies and problems with the glass back shattering etc. The headphone jack relocation is minor design change. iPhone 6/6s & iPhone 7/7s - I believe the 7 has been designed as an evolution of the 6 series and at this moment Apple could possibly release a 7s next year with the same design. But that will depend on the uptake for the 7. Again they may be forced into an 8 redesign early... So basically the original, 4 & 6 were really the only true redesigns so why are we so shocked about the 7? I think it's only been the market that has forced apple's hand when they have stepped out of their planned cycle of a new design every 4 years with a refine of the original concept every 2 years in between. But to be fair the have reacted when the demand dictated...3G model, bigger 5 screen, larger 6 screens so a completed redesigned 8 to compete with Galaxy and Note models could be likely.
