The embarrassing UFC loss will/would hurt Punk. Also I'm pretty sure he's too proud and stubborn to even entertain the thought.
If he were to wrestle, I'd see him in RoH or New Japan, agreed.
But I see him in Bellator for at least one fight before calling it a day in the MMA world.
In terms of WWE booking, I don't really think Punk's UFC loss would hurt too much. Lesnar won his fight last year and got squashed by Goldberg.
However, I do agree that Punk wouldn't really budge on where he stands. ROH would be the #1 in my opinion. New Japan would be pretty awesome though.
To me, Bellator has kind of a bad reputation. It seems like the "TNA of MMA". Anything is possible though.
I meant in terms of being over. He'd get "2:14" chants, and people might have a hard time buying him as a credible threat. He also made pro wrestling look bad in his UFC debut.
Okay I get what you're saying. I don't know if that's an absolute. Only one way to find out though.
