The Moto X Pure has not even shipped yet and we already have some developers working on CyanogenMod 12.1. The Galaxy S6 is several months out and still doesn't have even an unofficial build of CM! This is the beauty of a developer friendly unlockable bootloader device.
Developer "Shawn5162" is looking to become the official maintainer for the Pure. He has already started development on the kernel source, vendor tree, and device tree. The Github is here.
Shawn has already ordered the device but if you can provide partition tables, model numbers for all moto x devices, boot radio value for all moto x models that would be helpful.
