2016 might be the first year it might be a mixture of a tick and tock. It is supposed to be a tick year and look totally different but it looks similar to the 6 series while adding refinements to them that the s models do. And iOS10 might be a bigger update than what people realize when that is also usually reserved for the s years. Tick focus on hardware, tock focus on refinements and software.
In my honest opinion, the iPhone 6 series is ugly especially on the back. Maybe 6/10 at best in design. The iPhone 7 isn't any better looking but a space black could cover up the ugly antenna lines. But here is the thing, Apple might move back to the glass art museum from the 4 series and that material just isn't practical to my needs. I don't like the idea being stuck with all-glass for three straight years.
Companies make these beautiful all-glass phones only for customers to cover up these phones which defeats the purpose of flaunting it. Glass shatters, too slippery, fingerprint magnet, the rear glass tends to be weaker, etc. I am getting iPhone 7 because of practical features like waterproofing and wireless charging. Somethings far better than pure design. Practical features.
^ Bleh design. But it isn't preventing me from getting it. Had a glacial silver One M7 which had far better antenna lines on the back because white and its silver tended to mesh well. The problem was the white lines would get dirty. So when the gun metal M8 came out with black lines, it resolved it.
Rose gold option for the 6s and SE? No, thanks. The space black iPhone 7 should improve the back with its dark lines meshing with its rear color. And it is a color option far less sissy than rose gold and gold where it looked like someone urinated on the back and the stain didn't go away.
