ARM chips and UE4

Are there any plans for UE4 to be able to deliver to native RISC architecture chips? Correct me if I’m wrong, but right now any x86 solution is emulated on an ARM chip, right? So with the increase in popularity and with Nintendo NX coming out with one of these, and with the possible increase in performance in the next few years, is there going to be a shift away from CISC?

Pretty sure the Nintendo Switch is using an 8 core x64 arm chip.
