I don't understand why everyone is ignoring the simple answer that no 3D touch is simply a result of the same 5S screen being used? Presumably 3D touch requires a haptic layer on the screen so if that's not present, it can't exist.
Dare I ask why I'm being downvoted? As far as I can tell, [1] suggests that there's additional hardware involved in the screen to make 3D touch work. Is it that this hardware exists but just isn't being used? Is it that people think it's a trivial addition to revise the 4" screen to include this hardware and that Apple were just lazy?
I'm genuinely curious, because I have not seen anyone say "hey maybe they just used the same screen as the 5S and that's why 3D touch is left off" but I have seen a lot of "I don't understand why Apple neglected to include 3D touch in the SE".
