You would be able to buy an iPhone pro, because there wouldn't be one. There would only be a iPhone mini, iPhone and iPhone plus. The plus can have an extra feature but would be nice if the 4" had everything that the 4.7" did, which is totally doable. All I am saying is Apple needs to streamline things alittle. I have seen customers walk out of the store with nothing but a headache trying to decide what size they won't and what features they will and will not get.
IT is prettig naive to think there won' t be aan iPhone pro.
My guess is March/April 2017 with oled and an all glass design, launched with the 2 new iPad pro' s. But I could be wrong of course.
The point is: there will be an iPhone pro in the next 2 years. Plus will be just an iPhone with a bigger display and higher res.
Pro will be with a bigger display, more ram, upgraded soc, better camera(?), and other features and tech specs that are just not ready for the mass production in big numbers and have high manufacturing costs at that time.
A year later features of the pro will be released in the regular iPhone an iPhone + models.
The pro will be about $100 more expensive than a plus model, so we basically have to pay for the low yields and R&D costs, while Apple will maintain their margins.
