Bethesda didn't really use to have dedicated press conferences before the E3 2015 showcase, where the company showed Fallout 4, Doom, and Dishonored 2 among other titles.
The showcase was quite successful and Bethesda did it again for E3 2016, where Quake Champions, Prey and once again Dishonored 2 were demonstrated. Still, we had no clue about Bethesda's thoughts on repeating the show at E3 2017 before today.
Speaking with Metro GameCentral, Vice President of PR and Marketing Pete Hines stated that Bethesda's E3 2017 showcase is a likely event.
Probably, given what I know about what we’re gonna have going on next year, and what we’re gonna have to talk about, I would say that we’d probably have enough stuff to fill the time. And again, mostly because I really continue to like the idea of being able to talk to everybody about what we’re doing at the same time. So yeah, knowing what I know, I think we would probably do another one next year.
This seems to be a pretty huge hint by Pete Hines that the company has strong games in the pipeline to show at E3 2017. What could those be? Certainly Arkane's Prey, which is due for release next year.
Other than that, it'll probably be time to reveal the next projects from Swedish studio MachineGames (the creators of Wolfenstein: The New Order and Wolfenstein: The Old Blood) and Japanese studio Tango Gameworks (which made The Evil Within), whose President and CEO is Shinji MIkami of Resident Evil fame.
As for the next project by Bethesda Game Studios, considering that the Fallout 4 DLC was just completed with Nuka World, we will probably have to wait for E3 2018 to see that one.
