I find it strange that so many people are taking an internet rumour on face value and assuming next year will be the big update.
How often are internet rumours a year in advance true? They don't start getting any kind of truth until a few months before release. Remember the iPhone pro that surfaced with its 3 pin connector on the back? that ended up being wrong and that was doing the rounds until about a month ago.
What if there is an iPhone 7s next year with incremental upgrades? What if the iPhone 8 isn't what the rumours say?
Of course it's everyone's choice but I think a bit more scepticism is needed and not believing every rumour so far in advance.
Because people will believe what they want to believe.
So because 2017 marks the 10th year, people believe Apple is going to wow us.
The truth (as I see it) will be that the 2017 iPhone will have -some- new goodies (like they do, every year), but not an earth-shattering number.
Apple is very careful and calculating.
They parcel out new features on a very measured pace. Whether it's a new screen type like OLED, new technology like 3D Touch, or even a new color like Jet Black.
Very few things they do is by the seat of their pants.
The fact that the flagship of the line is the Plus since 2015, and with possibly an iPhone Pro debuting next year as the new flagship...they are sure to have features that won't be in the smaller phone.
