I'm guessing they are putting doubt in people minds and he will show up at Revolution or in Dynamite in March. So people will be happy and excited again.
I wonder if he genuinely hasn't signed or if they are desperately trying to silence it
Remember Moxley was surprise signing for Double or Nothing. Santana and Ortiz where surprises for All Out. Jake Hager was surprise for first Dynamite. AEW didn't announce the signings before there debuts. So this is a common theme for them.
