#3 AEW has expressed their interest in getting Moxley
It is a well-known fact that Jon Moxley is filming a movie at this moment. However, Dave Meltzer from the Wrestling Observer said that AEW was very interested in signing him down the line.
We all know that the interest of the talent and the promotion he/she wishes to sign with needs to be reciprocal. The very fact that AEW is interested in signing Jon Moxley pretty much reveals the fact that AEW will be Moxley's home sooner rather than later, because AEW is probably the biggest promotion he could potentially sign for, after WWE.
Meltzer does go on to say that there was no indication that Jon Moxley would appear at AEW Double or Nothing. But the thing about Moxley is how private a person he is, so every move of his is shrouded in mystery.
He could swerve the world and nobody would actually see it coming.
