Last year, Bethesda made the incredible announcement that mods would finally be coming to consoles, thanks to them extending support for official Fallout 4 mods to the Xbox One, and a short while afterwards, for PS4 too. And they stuck to their word- mostly. Fallout 4 mods launched on Xbox One as promised and scheduled, but the PS4 launch of the functionality was mysteriously delayed at the last minute, causing quite a few fans anguish and anxiety.
As of right now, then, there is no update on when we can expect new information for Fallout 4 mods on PS4- though Hines has promised that he is trying to get something new to share as soon as he can. Till then, I suppose PS4 players have to content themselves with hoping Bethesda have this sorted out by the time The Elder Scrolls Skyrim: Special Edition launches, because one of the big selling points for the console versions of that remaster is mod support for consoles, too.
