Obsidian has done a mainline Fallout before, New Vegas, so there’s precedent. And apparently Tim Cain (original Fallout, created the series) guy just showed back up in the last few months and is working at Obsidian and said that he plans to do one last game before re-retiring. And Josh Sawyer is there, and he directed New Vegas.
EDIT: And John Gonzales, the lead designer for New Vegas.
And Bethesda has said that they’re gonna be contributing.
That’s a lot of mainline Fallout head honchos in one place. First time I think that all of those have been together.
I mean, yeah, I guess it’s not impossible that they’re gonna do a spin-off, Fallout Shelter-like, but my money is that it’s gonna be mainline.
EDIT2: By “mainline”, I’m including Fallout: New Vegas, even if it didn’t have a number, fit between Fallout 3 and Fallout 4. I don’t think that many people would call that a spin-off.



















Whatever Fallout Obsidian is doing is happening now, not after the next Elder Scrolls game is done.
Might not be Fallout 5 — Obsidian’s last Fallout game was Fallout: New Vegas, which I’d consider mainline, even if it fit between Fallout 3 and Fallout 4 and didn’t get a number.
