I think that depends on the pace at which Android is developing. Android hardware is incredibly low priced and there isn't a significant difference between iPhone and a mid range android phone in terms of hardware. If the quality of the OS experience is as good or better than Apple, then Apple marketshare will shrink eventually. They are still making a killing in terms of profit margin, and shifting a lot of units so as a company I'm sure Apple will continue to do well for a long time. Android struggled for a long time with user experience and visual quality, but Android 5 and Material Design has been a huge win for them and I'm pretty sure that trajectory will continue.
