Looking past 2018, Bloomberg projects that Apple will remove the Lightning port from the iPhone X. Considering that it already killed the headphone jack (RIP), removing the Lightning port would make for the first truly cord-free phone. Earlier rumors contradict this, suggesting that Apple will merely exchange the Lightning port for a USB-C. Truthfully, I'm hoping for the latter.
