IMHO - If Cena hadn't busted his elbow for real, the rivalry would have come to a heads at HIAC, no doubt.
The problem is now that Ryback, who was only pushed in to the limelight cos of Cena's injury, has gotten over pretty well with this whole manufactured beef with Punk, so it's essentially left us with the following situation :
Cena vs Punk, which has been going for a long time now, still not resolved.
Ryback vs Punk, which was obviously only meant to be a fill in (til Cena recovered) has now also become an unresolved story line (thanks to Maddox) and really, only started backstage after Raw when Punk floored Foley.
The problem now is going to be that both those rivalries are getting pretty decent heat and getting over with the crowd, so what happens?
Does Cena get back to business with this fued with Punk, and Ryback suddenly gets moved back in to the shadows, or do we see Ryback continue to get the push, leaving this whole 'Cena & AJ' angle?
