I am sure that is in the mix if they phase out the 3.5-mm connector in the iPhone 7. Can see why they are going this way as the real estate for this connector can be used for other components such as touch sensing to the left and right of the home button.
There will be the usual "connector switch" complaints and drama similar to transitioning to the Lighting connector from the 30-pin connector. Those with money upgrades to buy the new stuff. The cheap ones will complain with anyone of value not caring about the complaints.
