343 Industries confirmed it won't be lifting the curtain on Master Chief's next adventure for a while yet, IGN reports.
The news came courtesy of a blog post on Halo Waypoint:
"We won’t be talking about Halo’s next major title for quite some time. 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."
We knew Halo 6 wouldn't be at E3 2017, but apparently the game is further from reveal than initially thought.
A digital expansion was announced for Halo Wars 2 during E3 however; Awakening the Nightmare, giving the Banished their own single-player campaign as well as bringing back the Flood.
