I can believe that the 3.5 jack will be removed, but only to be replaced with more convenient open and not proprietary standard--analog standard. I can live with USB-C, that, btw, already has analog audio implemented, when it de facto becomes industry standard for audio output. Just hope they solve simultaneous charging with headphones plugged. Two USB-Cs may be.

But definitely it is not going to be proprietary lightning digital audio port that requires external DAC and licensing.
