The 6S is already water resistantWater-resistance. Flush Home button. Dual-cameras. A monster of a chip. Possible wireless "AirPods". Possible screen resolution bump. True-Tone and Wide Gamut display. Quite a big bump in battery capacity (more so than previous years). New iPhone colour. Dual speakers. Regardless of what everyone things it's a new design. New materials etc.
Just because it looks similar, doesn't mean it will be similar.
Don't expect "innovation" every year. It's not going to happen.
If nothing excites you from that list, switch to Android but you'll be coming back next year when they release the iPhone 8 so...
Flush Home Button? Making the home button harder to find without looking is a "feature" now?
Dual Cameras = Gimmick which has been proven by other makers who have implemented it
Monster of a Chip, because any app out there has yet to come close to stressing the A8, let alone the 9 or 10
Possible wireless Airpods, that will just as well on every iPhone at least as far back as the 5S
Possible screen resolution bump? No. Zero evidence of this anywhere in iOS 10, zero rumors about it
TruTone and WG display? Maybe but probably not. No rumors, no evidence
Big Bump in battery capacity? Best case scenario we are looking at an increase of one hour, hardly "big." My 6S already lasts all day with only occasionally plugging it into my car while driving.
New color. Ok? I'm sure the 2017 iPhone will also be available in that new color as well.
Dual speakers, maybe. There's just as much evidence pointing to no dual speakers, so it could go either way.
Don't expect "innovation" every year. I'm sorry, what? Maybe this is the case with Tim Cook's Apple, but it certainly wasn't with Steve Jobs's Apple. This is not something Apple supporters should be ok with, let alone making snarky excuses for.
Finally, "switch to Android?" Why would I "switch to Android" when I just said I was perfectly happy with my 6S? I'm sure the Note 7 is a fine phone, but I have no interest in buying all of my apps all over again for a different ecosystem when I'll more than likely be upgrading to the 2017 iPhone in a year.
