TL;DR

Fallout 5 has officially been greenlit, with development moving ahead—even if we still don’t know which studio’s running the show. According to Windows Central’s Jez Corden on the Xbox Two Podcast, Bethesda’s main teams are tied up with Starfield DLC and The Elder Scrolls VI, so the new Fallout may land elsewhere.

Oh, and in a twist, this push for Fallout 5 reportedly led to ZeniMax Online scrapping its in-the-works MMORPG.
