Per this Goldman Sachs note today (h/t Business Insider), prices are expected to decline due to Apple’s increasing presence in emerging markets and its entry-level iPhone SE:
We expect blended iPhone [average sales price] to decline 3%/3%/1% in FY16/FY17/FY18, primarily driven by a greater shift to emerging markets, where we expect a higher mix of lower-end SKUs such as the iPhone SE and its successors.
