Default [Q] Questions about 4.4.2's camera

Does anyone know if the camera from the new release is compatible with 4.3 MK2? I've heard a lot of good things about the new camera in terms of speed and focusing better. I'd like to get it, but not a the cost of losing root and SD card writability/usability.

If it is, can some kind soul pull the camera out of NC5 and give me a way of downloading it?
