No but I saw they mentioned on twitter there were other references
I was just joking though, but imagine if it were true. Would be one of the greatest works in wrestling history if it really were Punk though.
I preface this by saying I believe 100% he'll be at Survivor Series to start his WWE nostalgia run but I could see Snowman actually thinking about going through with bringing Sourpuss Punk back (again) for a couple reasons:
1) Full Gear is a week before Survivor Series and it would be a way to stick it to WWE
2) They need to do something to spark ratings/buzz for the TV rights negotiations
3) He was already getting mixed reactions before All In, so might as well make him a full-on heel. Adam Cole is on the shelf for months (and unable to turn on MJF) and Jay White and Swerve are probably losing at Full Gear. The only heels right now who would be believable enough to take the belt off of him that wouldn't be coming off of losing a feud are Samoa Joe (who MJF beat a couple months back), Christian (who is in a program that's going to lead to a match with
Edge Adam Copeland), and maybe Malakai Black (but it looks like HoB and BCC are going to be feuding for some time). Plugging Sourpuss Punk back in there for him to take the title at Worlds End (taking place on MJF's turf of all places) with this devil thing actually makes logical sense.
