Fable and Elder Scrolls 6 were discussed in multiple interviews by Phil Spencer. In this case, he accidentally revealed Elder Scrolls 6's release date by discussing Fable's release date. Unfortunately, it's awful news for fans of the series.
The first version of Skyrim came out a decade ago. It's crazy that Bethesda doesn't have a team for Fallout and one for Elder Scrolls 6. They have a huge studio that doesn't have the employees to work on their flagship games like Ubisoft and EA.
The Elder Scrolls 6 release date will be 2024 at the earliest
The Elder Scrolls 6 was announced alongside Starfield at E3 2018 before Xbox acquired Bethesda. Starfield will be released next year. However, there is no word on when The Elder Scrolls 6 will be released. This is why we must speculate with the information we have now.
At this point, we do not even know if it is an Xbox Series X exclusive. Currently, it doesn't look like it will be coming to PS5, but this hasn't been confirmed.

Phil Spencer discussed the release of Fable and The Elder Scrolls 6 in one of his interviews. Fable would be released before The Elder Scrolls 6. Now it looks like Fable won't be released until 2023, and that means The Elder Scrolls 6 won't be released until then.

However, there's a reason for this, and that reason is that it's not yet ready for release. Bethesda has more than one team working on games at their studio, but one always gets more attention than the other. Starfield is getting a lot of attention at this point since it is coming out in 2022. So we'll just need to wait a long time for The Elder Scrolls 6
