You guys are giving them WAYYY to much credit here. This is the creative team that DQ'ed Batista in a chairs match
But here's my take:
They'll run the same match they've been going through at house shows with some added cell bumps in there. Near the end, Heyman will bring some wire cutters (Like HHH did) to get Punk out of the cell just as he rolls out of a getting Shell shock and locks Ryback in the cell. Punk and Heyman escape through the crowd and laugh at Ryback until he either rips a hole in the cell or breaks open the cage Big Show/Mark Henry style and chants FEED ME MORE! from the barricade as Punk and Heyman either looks scared from the Mezzanine.
Alternate: Ryback only breaks out after a camera shows them leaving the arena in a car and he chants at the jumbotron.
