The Lightning port is never going away. Apple makes $4 from every third-party manufacturer who uses a Lightning port on a device or a cable, its a significant part of their profit model. And this has been going on since 2002 and the 30 pin connector. It would take an act of God for Apple to walk away from that kind of free money. It's one of the reasons that the headphone jack went away. Any maker of a wired headphone now has to pay Apple for the privilege of selling a compatible wired device. Note that Apple pays a royalty for Bluetooth and USB connectors, costs them millions in revenue. Bluetooth reluctantly has to be included in an iPhone, USB does not. This is also why the MacBook has the 'controversial' single port. Apple has to pay a license fee for every USB-A, HDMI, SD, VGA, Ethernet port on its devices. This stuff isn't free. Big companies own, patent, and license these technologies.
