Unfortunately, Trejo's wish wasn't included in Bethesda's official lineup for Fallout Day. During the celebration, the studio is set to show off more from Fallout 76's upcoming Burning Springs expansion out this December, and yes, that includes Walton Goggins returning as The Ghoul from the hit Fallout TV series. There are also updates coming to Fallout 4 and Fallout Shelter, plus new content via Creations, Bethesda's name for officially supported community mods.
I don't think they will, but I think they should do a remaster of the first three. One of the things that we pitched at one point pretty softly, was to kind of retroactively, rebrand the first three games as if they were a trilogy. Call it, like, the Champions Trilogy.
