Could be a mix of the PR department and economist working at Apple trying to fabricate excitement. For what I do with my iPhone 6s, Apple better come with something like free money maker for you or free data plans.
I think the shock of market saturation is just not reaching some people at the company. Apple, if you want to get people to upgrade, and I mean really upgrade from a more than good enough 6s and iPhone 6 (2014), you would need to do this:
- Equal features and functions between iPhone 7 and 7 Plus - no compromise, so OIS, Dual Camera, memory, A CPU.
- 64 GB storage on cheapest model
- Price drop of $100
- 15 GBs of iCloud storage for free
- 3 months of free Apple Music
- Half off on a new bumper
- Trade in deal for iPhone 6s, so I could send in my 6s 64 GB and get half on a iPhone 7 64 GB
- Keep the head phone jack - you need it especially when you are in a library or doctors office
- Expanded use of 3D Touch, then again, this should not be limited to iPhone 7
