Offensive Bias was the lack thing mentioned. I think it's supposed the big mic drop cliffhanger of the scene. So I definitely think it's going to play a role in the future.
Again, not having played the game myself, the story does seem like it ends at weird spot. When that Bloomberg article mentions that 2/3s of the game was cut that statement might be literal. Having the one biome and there being no brand new enemy faction to fight in what is supposed to be the start of a new saga definitely suggests to me that campaign in Infinite was supposed to be the first half and then you would go to other locations to fight the Endless. The cut content would also explain why there are screenshots of stuff that didn't happen in the game. But definitely in the next campaign the Endless will for sure be a new faction to fight. I'll be curious on how and when 343 will deliver the new story stuff.
ya cut content happens, not exactly shocked by that. Honestly, the way the stories were structured, it being longer just would not have worked imo. It felt contained and controlled in a way that having the second half with the endless just would have been kind of exhausting. If it retained the old linear structure it could work, but with it having a more open zone design, having that other 2/3rds would have def over stayed its welcome. I think this story is the better result. This ones focus was on resolving cortanas fate (wonderfully done imo), explaining the banished (could have been better but enjoyed it and appreciate Atriox's focus on the last levels) and why they are on zeta halo and then introducing the next arc.
The offensive bias thing could point towards its involvement later or just be a name drop for the sake of name-dropping it. I mean, both that and mendicant are the most important AIs ever so them just being mentioned in verbal dialogue in a game is pretty major.
