I think Moxley has been so good this summer that the original plan went out the window and there was desire to legitimise his title run and make him the genuine champ. I'm happy with that, as someone who liked but never loved Moxley, because I think he's on an absolute tear right now. He should be the beloved champ and Punk should be a bitter heel. Obviously you couldn't and wouldn't want to do that match and outcome in Chicago. That said, I've no idea how All Out will play out if there will be a rematch in the main event. Punk taking the title off Moxley certainly turns him heel in every other city bar Chicago.
Worth pointing out AEW is in New York the week after All Out. One interesting fan theory is that The Pinnacle are going to be reformed with Punk as the heel leader having Wardlow and FTR join him, which MJF would then return and face off with.
In other news, the 6-man main event was fantastic. Will Ospreay looks golden right now and him vs Omega in the ring next week should be the start of something good.
