Looking at teardown photos, the "Taptec Engine" probably isn't going to be working anymore. But the primary reason seems to be for waterproofing.
Samsung devices are waterproof and have headphone jacks, so doubt that is it. I still firmly believe it is simply to sell more hardware. They have to put that Beats Audio purchase to good use.
