AEW All Out: 5 major returns or debuts that could possibly happen

#1 CM Punk

This could be the biggest return of this decade!

It all comes down to this one, doesn't it? Ever since the Elite announced their new promotion, the Internet has been buzzing with the talks of former WWE Superstar, CM Punk joining them. Even though Punk has himself dismissed any such alliance, even trolling fans who were expecting him to show up at Double or Nothing, many are still expecting him to show up.

The fact that AEW All Out will take place in Chicago, IL - the hometown of the Straight Edge Superstar - there are reasons for us to believe that the former WWE Champion might have one last run up his sleeve with the company that is being considered the biggest competition of WWE today.

One thing is for sure if he does show up at All Out, he'll arguably be the biggest star in the company (Sorry Jon Moxley). That right there would help them get the mainstream attention that they need to stand a chance to compete with McMahon's wrestling giant.

While Punk has stated in interviews previously that he is done with wrestling, his recent actions of appearing at an indie event under a mask suggest otherwise. Whatever the case may be, his return might just prove to be the biggest one of this decade.
