Someone posted the history of the 9th in the release date thread, after that no other date would’ve been as perfect.
My guess is that the video editor was a Bethesda fan and had Starfield in his mind from all the crying after the delay and made a typo when typing the date.
Seriously though, with 11.11.22 the release date would’ve overshadowed the game, nailing 2022 is already doing it, almost nobody is talking about the actual game only that it’s coming in 2022.
