iPhone 7 will be great phone and I will buy one, but iPhone 6/6+ was an exception because it introduced 2 new screen sizes that people where anxiosly waiting for. People switched to Android solely because prior iPhone's had a smaller screen. Also, there is no more "necessary" features left to add, just "cool" ones that may be useful. Processors are fast enough, Camera is good enough, there is a screen size to make everyone happy, 6S+ gets great battery life, Touch ID is secure enough, etc... I just don't see a groundbreaking feature coming that hasn't even been rumored about for the iPhone 7. Dual rear camera's seems interesting at best, waterproof design will be a nice touch, but not much else except the usual specs upgrade.
