At AEW Full Gear, Jon Moxley faced off against Kenny Omega in a lights out match, where the results did not count for the win/loss record. The two battered each other and it was a very bloody match. Ultimately, Moxley came out on top. However, Omega certainly has not forgotten about it.
On Wrestling Observer Radio, Dave Meltzer talked about a portion of Being The Elite, where it implied there would be a rematch between Moxley and Omega in a hardcore match. He said that there is a possibility we will get to see the match as Omega is obsessed with beating Moxley according to the story. However, he wants to beat Moxley at his own game.
It is unknown when that kind of match will take place, if at all, as AEW is not going to focus on such matches for a long time. We will get to know in due time.
