Irish's video isn't a one-of either. Battlefield 2042 won't contain the game's full story, EA confirmed, because it's being told in part through Specialist Stories.
"The narrative will continue to evolve over time as more Specialists join the conflict, each with their own story to tell, and pull players deeper into the world and lore of Battlefield 2042," EA said in a statement (thanks Polygon).

In this case, it confirms Battlefield 4's ending, proving that Irish survived (obviously, since he stars in the video) and that Huang “Hannah” Shuyi did not.
Beyond that, the Irish Battlefield 2042 video also introduces Oz, a character with different ideas for what the No-Pats' future should look like.
It's not certain if Specialist Stories will continue after Battlefield 2042 releases on October 22, but EA promised several more focused on the remaining five Specialists in the lead-up to launch.
