Fallout 4 mods will be on PS4 if Sony agrees
Fallout 4’s creative director, Todd Howard, was asked if Bethesda plans to roll out mods to Playstation 4. He said that the team plans to, but it’s dependent on Sony.
Howard told Digital Spy, “We will be. Well, we're going to make every effort to. If Sony says no, we won't, but I don't think they will. But, you know, it will come out on PC first. So early 2016, the creation mod for the PC, and then we're going to make that work on the Xbox One, and then we're going to do the PS4 version."
