Not really, AAA still has some say on it. The moment AAA told them to stop doing CMLL events they stopped.
I thought the word was that the AEW involvement was what caused them to drop out, since I thought they were slated to come back sometime this year before Double or Nothing happened and all of the official announcements and stuff kicked off.
That being said I'm sure they have a bit more loyalty (aka getting paid a lot) by AAA at the moment so they're on good terms enough to work it out. Irregardless I think they come to AEW with or without AAA
