God of War” director Cory Barlog appears to be teasing a sequel to Santa Monica Studio’s acclaimed Norse-mythology blockbuster. As a post by Reddit user “Kayfriso” (discovered by Push Square) points out, Barlog’s pinned tweet begins a Twitter thread that — when you take only the first letter from each tweet — ultimately spells out the phrase “Ragnarök is coming.” In Norse myth, Ragnarök is foretold as a final great battle of the gods, which is believed to cultiminate with the death and rebirth of the world.

Given “God of War’s” critical and commercial success upon release in April 2018, the idea of a sequel isn’t particularly surprising. A PlayStation 4 UI theme released for the game’s one-year anniversary in April featured the phrase “Ragnarök is coming,” as well. But it’s worth noting that although Sony has no significant presence at this year’s E3, Barlog himself retweeted IGN’s June 9 story about the initial Reddit discovery, suggesting that a formal announcement might not be far off.

The annual Electronic Entertainment Expo, better known as E3, takes place at the Los Angeles Convention Center from June 11 to 13. As is tradition, however, things kicked off early on Saturday at 12 p.m. ET with Electronic Arts’ EA Play event, which is being held at the Hollywood Palladium on June 8 and 9. Nintendo also hosted a number of esports tournaments throughout Saturday afternoon.

Microsoft will hold its big Xbox E3 2019 Briefing on Sunday, June 9, at 4 p.m. ET. Publishers Bethesda and Devolver Digital also have press conferences scheduled that same evening at 8:30 and 10 p.m. ET, respectively.

E3 2019 is coming to Los Angeles on June 11 through 13, and we’ll cover all the highlights of the event here at Variety as well.
