#1 Debuts during AEW's first show on TNT
It was recently announced that All Elite Wrestling is going to air their weekly television shows on TNT, which is the former home of WCW Monday Nitro.
As of this writing, we don't know the date of AEW's first show on the Turner Network, but the show is set to debut in the fall, and according to Cody, it'll likely be a two-hour long weekly show.
Of course, AEW wants to make a huge splash during their first episode of weekly television, and the best way to do that would be to bring in CM Punk as a surprise, or in an attempt to ensure that they have the biggest audience possible, they could announce the former WWE Champion's debut ahead of time.
However, in whichever way they do it in doesn't really matter, as Punk debuting in the company will be huge no matter what.
