As far as I am aware only PS3 games use MSF (and it's not just Bethesda games). I have researched PS4 4.05 Skyrim/Fallout 4 modding and I can confirm they do not use MSF.
But maybe a game on PS4 will suprise me. Although I built this tool with PS3 Skyrim in mind for those wanting to use mods with sounds, but this works for any other PS3 (or PS4 if it uses it) games.
