It looks like Halo 6 won’t be revealed anytime soon, as 343 Industries has confirmed the studio won’t be discussing the next major installment in its sci-fi shooter series "for quite some time."
In a post on Halo Waypoint, 343 Industries writer Jeff Easterling (aka GrimBrother One) addressed the absence of Halo 6 from Microsoft’s E3 2017 media briefing. "While there’s little to nothing that can be said on that front, it’s been made clear that we won’t be talking about Halo’s next major title for quite some time," Easterling said. "And no, that doesn’t mean Gamescom. Or PAX. Trust us, when we’re ready to begin pulling back that proverbial curtain, you’ll know. It won’t be soon."
