Fallout is all the craze these days, especially off the success of Amazon’s recent TV show (recently renewed for Season 2).
Nevertheless, it does add a bit more to the discussion on whether Bethesda should have worked on Fallout 5 instead of Starfield.
Director Todd Howard did confirm a sequel would happen at some point, but only after the launch of The Elder Scrolls 6.
Obsidian Entertainment of Fallout: New Vegas fame was theorized, or even a separate team from the main Bethesda Game Studios (currently working on Starfield and The Elder Scrolls 6).
