It's an interesting 1, both are possible, AEW it seems to be going that way, before the Starrcast announcement you never knew but being around so many of those guys either he could be signed or that could be an indication he's open to it. He will be mingling with them, he could arrange a meeting with them. Personally I'd like to see him come back to AEW. However Paul Heyman, they were cool, if they still are and Paul is the booker then might squash shyt if a great offer is made, Triple H could focus on NXT, Bischoff on Smackdown, Heyman on Raw, is F Punk is booked right it could be great, but it all depends on the booking and the story told. AEW would seem to fit Punk more, more freedom, you could imagine Khan would be going for him too, if he's gonna make a comeback at this point sooner rather than later would be best. AEW's schedule would be more flexible, financially WWE may be more willing to make a bigger offer, but both would want him with them.
