They're likely keeping the existing design to force people to the third/glass model (which will likely have a $200 premium, i.e. starts at $969 w/ 128GB of storage) This will undoubtedly push the ASP up, and that's Cooks only 'innovation' for the company ... sales numbers.
Yes agreed.
Keep the 7 and 7 plus. release a revised 7s and 7s plus in new colours, faster blah blah
and the the top end iphone pro with oled etc.. and thats gonna cost big big time!
If they can keep prices down - then the 7 and 7 plus simply disappear next year
