Even if the 7 is the world's greatest yet, there will still be an ocean of 5S, 6, and 6S out there that were not there in previous years. Unless they invoke a huge buy back program (complete fantasy), many secondary buyers will happily buy/be handed down the older, just as capable, phones and the 7 will STILL be pinched. Unless Apple and others can open significantly new markets, the days of wine and roses can be coming to an end for anybody's hardware. Their future (in consumer telephonics) probably lies in leveraging their ecosystem more than new phone sku's. IMHO, of course.
