He has such talent I can't think that no matter what he would have a place in the WWE, be it as a talent scout, trainer, occasional on air personality, etc.... that is if he wanted it. Even if this is the news we fear, I can see him coming back in a few years for a big match or two, especially if the right opponent is lined up and could really use the rub.
Lets not get ahead of ourselves though. This might be good news or at least not the worst news. Maybe it is the rumble. Maybe he is announcing that he shaved his beard. Maybe he and Bri are going to make person. Maybe he is announcing himself as Punk's first MMA opponent. WHO KNOWS!?!?!
