It is worth noting that Kazuchika Okada and Tomohiro Ishii are both currently in the United States.
Orange Cassidy and The Best Friends were announced as the newest members of the Chaos stable this past Wednesday on AEW Dynamite. On commentary, the announcers name dropped Okada's name several times and AEW usually will not tease someone unless there are plans to bring that person in.
At the end of Rampage, Cassidy lost a Lumberjack match to Hardy after constant interference from members of the HFO and others around ringside.
It appears that Ishii or Okada or both men might be appearing on AEW programming soon.
