I'm not gonna read back through the whole thing, so will just throw my initial thoughts on stuff in here.
Part of me finds this report super suspicious. Like AEW has pretty much kept everything they do super tight lipped to the points where no spoilers come out. Show and Henry were never speculated, same with Christian I think until Tony threw the hints out there. I don't think even Sting was leaked, just assumptions were made because of his stuff being pulled from wwe.com etc. Now with arguably their biggest signing, a higher up starts floating stuff out there? Odd. Either people are gonna get disappointed if he never shows up now or a genuine surprise has somewhat been ruined as people are gonna keep expecting it.
Would be interesting to see how he was used though. It's based on absolutely nothing but I feel like he would want the same deal that he basically hated other people getting in the WWE, get paid the big bucks to come and do angles at the top of the card here and there and taking away opportunities from the other guys who are there every week.
