Bethesda has already confirmed that it will hold a press conference at E3 2019. However, the company confirmed at PAX East that it would not be showcasing or revealing any details for either The Elder Scrolls VI or Starfield at the event.
In regards to details about a new game engine, Bethesda executive producer Todd Howard issued the following statement during a panel at PAX East:
"That's just a little sneak peek at the technology that we've been building, people are going to see (the tech) at first, actually, in Starfield. And so that tech will have like the second version of it in TES6, and--before everyone asks--please be patient. It's going to be a long time. It's not something we're going to be talking about at E3--either of those games--this year. And so patience, please. But given the (Elder Scrolls) anniversary, we did want to give everybody a taste."
It's not a surprise that this is the case since the trailers shown at last year’s E3 implied that both games are still in early development. Additionally, Howard has stated that he already knows the release dates for both titles, but he hasn’t shared any further details as it "would be foolish to say it," as he puts it.
But while we wait for more on TES VI and Starfield, Bethesda has plenty of other titles to keep us busy. The Elder Scrolls: Blades early access is out right now. Additionally, Rage 2, Doom Eternal, and Wolfenstein: Youngblood are all scheduled for a 2019 release.
