The very open Pete Hines, VP of PR/marketing at Bethesda, showed up on YouTube's E3 show to give some info on what they're currently working on. As well as a little chat on the sequels for Wolfenstein and The Evil Within, he talked about The Elder Scrolls 6 - it's still not in development. Perhaps worse, it's third on the to-do list.
For some stuff that's actually getting made, here's all the upcoming PC games.
You can see the full interview above, with the TES 6 chat starting at around the nine minute mark. In response to rumours started last year, Hines says that TES 6 makers Bethesda Game Studios "have at least two major titles that they are working on before we're gonna get to Elder Scrolls 6."
He later clarifies that "TES 6 is not in dev while we work on [those]." He also makes it clear that there's other stuff going down there at the same time - like Skyrim for Switch.
