The Wrestling Observer Newsletter is reporting that as of now, none of the wrestlers in AEW are scheduled to be on either of NJPW’s Wrestle Kingdom shows at the Tokyo Dome in January. It was noted that this isn't necessarily locked in.
Some things to consider according to Dave:
American talent would have to fly out by December 20 to appear
AEW will not be taping on December 23 (that show will be taped on December 17) but there is a taping on December 30
