Default 120fps recording on the nexus 5?

I saw this link

http://forum.xda-developers.com/show....php?t=2548974

Where someone posted a mod for the G2 where they enabled 4k video and 120fps recording. I am interested if we could do this on the nexus 5?

Is it a hardware limitation? I'm pretty sure the s800 can handle it and the camera can snap a picture in 8mp resolutions, so I would think you could mod it to record video in 2k, or 4k resolutions.
