This shouldn't be surprising. Rules are rules. Everything must come to an end, including iPhones. However they still have good ideas left to keep the iPhone alive:
1. Smaller bezel
2. Camera upgrades
3. Thinness
4. Auto stereoscopic Display
5. Integrated TouchID
6. Bendiness
7. Shatter proof display
8. Shatter proof body
9. Faster processor/graphics
10. iOS Device to PC docking transitions
11. Hologram projector
12. Smarter Siri
I probably just leaked Apple's iPhone Roadmap. So they are pretty much set for the next couple of years.
