Is it not just possible that we don't actually know what the 7 will be like in terms of features because they haven't leaked (yet) maybe as we get closer to September we will see more and more leaks (like the 6S). At the moment what we think we know is:
No headphone jack
6S like design
Dual camera (for 5.5" or iPhone Pro)
None of that says much about the features of the 7, even the 6S had some good stuff, 3D Touch, 4K video, 12 MP camera, so it's only natural to assume that the 7 will carry on from that.
