I honestly think Punk is just burned out by the WWE schedule. If his deal does in fact expire I think he would just take the rest of the year to rest/recouperate and likely return sometime around the Rumble. But, if for some reason he doesn't go back to the WWE I would be bummed out, being that he is easily my favorite wrestler currently, but If I remember correctly he said in a shoot interview before he signed with the WWE that he never had any intentions to work for Vince.
