I'm leaning towards yes, despite the walk backs from some insider, they're still claiming it will be announced on Monday and the launch itself had a slight delay due to a 'bug'.
What we have so far.
- Nov 15th was listed in the Store ID for Halo Infinite - 343 has now edited this back to December 8th.
- Nov 15th is listed in the Waypoint API for Halo Infinite - Still hasn't been edited.
- Pringles listed Nov 15th as the release date (Lol) - They've removed this but only from public view, it is still counting down to Nov 15th but now hidden.
Then Bonnie Ross was meant to be at Fanfest yesterday but couldn't make it as she was pulled back to 343 that day for something that is "of such high importance".
We'll see in a day at least, I think the biggest thing is that 343 hasn't denied it, there have been multiple rumours about Halo across the past year and 343 have instantly shutdown almost every single one within a day, this has now gone on for 3 days and there's not a single word from 343.
I think it's being announced with a launch later in the week or next week, MP will be locked behind Game Pass until December's release, Imo, an early access period sorta for Game Pass members.
