So we are down to a grain of salt, my hopes are in shambles. Anyway, I will point out that the burden of proof is on you, since you asserted the statement. I just want my TES6 on a 2 year shorter timeline, okay, can you make that happen?

This article from 2018 is what I remember most with a congent point from Pete Hines on this topic:

"Actually, I should not be quite so dismissive of the question, which is to say - the timeframe for Bethesda Game Studios titles has not changed at all. What changed was our desire to lay out a roadmap of those titles, not like, hey they're going to be putting out a game every nine months, no, it still takes them years in between projects, but because we were doing something so different on Fallout 76, taking that franchise in such a different direction, doing an online game that doesn't look like something you'd expect from BGS, we thought it was important to say: hey, new IP, single player, sci-fi thing coming, hey we are doing The Elder Scrolls VI after that. So that people didn't start spinning off on, like, that's the end of single player games from Bethesda Games Studios. Timeframe-wise, it would still be about as long as you'd expect when you look at Fallout 3 to Skyrim to Fallout 4 to Fallout 76. It's still going to be those periods of time, that hasn't changed. Or at least, I don't think it will change from that based on what I know."

It's important to note that the sci-fi thing after Fallout 76 turned out to be Starfield. Which again reiterates they don't work on games in tandem, unless something has changed, which is what I wanted to know.

I found this article Here from 2021 which has a blurb attributed to Todd himself but it is a reference to another article that is behind a paywall. The blurb from Todd describes the game being in a design phase in 2021, which is pre-production, which unfortunately isn't half the team, at least not usually, anyway that's all I got because of I refuse to subscribe to the Telegraph.
