Nikkei Asian Review is reporting Apple is moving to a new 3-year design cycle for the iPhone:
The new version slated for this autumn will look almost identical to the current iPhone 6. Functions such as the camera, water resistance and battery capacity will likely be improved, and the headphone jack will be removed. Also, a high-end version of the model will give users better-quality photo capabilities via correction functions.
This makes sense considering the leaks this far.
