You really can’t get any more direct and explicit than what the 343 Industries Community Manager told fans on the Halo subreddit.
There’s been a bit of discussion about the potential for Microsoft and 343 to show off a new Halo game of some sort at E3. Some folks were thinking that might mean a remake of Halo 3, like a Halo 3 Anniversary edition. That’s not happening. Clearly.
The exchange on Reddit saw a user or two lean towards the possibility of Halo 3 Anniversary being a real thing when Brian Jarrard piped up, succinctly, with ““OMG stop. There is no Halo 3 Anniversary.”
I love that. I love that he was so quick to shut down the speculation with such an obviously exacerbated reply. He must be getting that question a lot.
So, expect something from 343 Industries at E3 2017, but don’t expect it to be too colossal or related to Halo 3 Anniversary. That one, friends, seems like it doesn’t even exists.
