A closed event does not mean we cant see what happen that day, but is very suspicious.
Since the event is on 20th anniversary, they sure are going to release a Trailer the same day, for the eventual Oath Game.
I can't believe they can annunce a new KH in 2022 , not showing at the world . 2022, we are in 2022, and the pandemic is like speed up the process. Every event or almost is online now
BTW, I want to see Quadratum in the Trailer, and atleast 1 playable character for that game....
But probably we'll see another Gacha too.
The concert and the rest, SE can upload them later or when they want.
