Apparently CMLL's partnership with ROH and NJPW could be over soon. The Rush/Lee situation seems to have been the tipping point.
ROH has been upset with CMLL for a while due to their restrictions and streaming issues for shows which has affected ROH by association. They also would be willing to end the CMLL relationship if RUSH's ROH title reign ends up being a big success and CMLL tries to cause problems with it.
NJPW also has some unfavorable views of CMLL and have no problem ending the relationship if it meant getting to keep Dragon Lee and not have to deal with any headaches from CMLL. NJPW is willing to keep the relationship active till at least next January for the Fantasticamania 2020 tour but also have no problems with dropping it either.
Then you have other issues going on like a potential mass exodus of young talent happening soon in CMLL and Rev Pro might also consider ending their ties with CMLL if CMLL causes any problems with their British J-Cup plans.
