The Elder Scrolls 6 was announced on June 10, 2018--that is now a full eight years ago. In the 2,920 days that have transpired, Bethesda has not released a single new image or trailer for it, or even discussed the game in an official capacity beyond small quotes here and there.
The game did not show up at the recent Xbox Games Showcase, prompting some people to wonder how it's coming together and when Bethesda may show it off again. Xbox chief content officer Matt Booty addressed this in an interview with Variety, saying one of the hard parts of his job is deciding what to show, and when, during high-profile showcases.
"You want to get them excited early, but we also know that we want to wait till the right moment. And when you decide to show it, you want it to be the best you’ve got," he said. "And also that when you show the game, you’re also giving them a promise of, hey, it’s coming soon."
https://www.youtube.com/watch?v=BQcnDNd3P7QBooty was speaking generally here, but he also talked specifically about The Elder Scrolls 6. He said he has sat down with game director Todd Howard as he played it, and Booty remarked that the game "looks amazing" and is "coming along well."
As for when Bethesda may show the game again? The developer is waiting for the "right time," Booty said.
Howard has questioned whether it was the right call to announce The Elder Scrolls 6 so early. “I have asked myself that a lot,” he said. “I don’t know. I probably would’ve announced it more casually.”
He later said announcing The Elder Scrolls 6 in the way that Bethesda did was "not my preference," but it happened anyway.
He went on to joke: “Just pretend we didn’t announce it. It doesn’t exist. No one has heard a word.”
One of the reasons that The Elder Scrolls 6 might have been announced so early was for the purposes of recruiting staff to work on it. This is a common practice in gaming.
