JohnMc1 - Is it really that shocking that he may never fight?
Not really. If Punk would have fought not long after he retired from WWE there might have been some interest left. Punk hasn't even wrestled in like 2 years now I'm not even sure they care to see him fight by the time he does.
I feel that it's far more likely that the potential "big annoucement" would be about his nagging injuries, and surgery delaying his debut, or possibly prevent him from fighting altogether- than it is likely that he will be co-main eventing UFC 200, IMO. I just don't see that as being realistic.
