I can't see them pulling Punk entirely unless absolutely necessary. I lean toward believing the WWE press release over believing meltzer.
I can see them working an angle to combine the Cena-Ziggler ladder match with the TLC match, thus lightening Punk's workload (as suggested earlier) and allowing him to "sneak" a win in the end, which was probably the plan in the first place since we're all fairly certain that the Shield will be interfering in the match regardless. They've gone too far to build up the Rock-Punk match at the Rumble for them to back off of it lightly now.
Of course, if he can't go at all, that's another story.
