I'm still sticking with Punk winning the belt. New Nexus rushes the ring to celebrate, but turns on Punk for leaving them behind and leaves him a mess in the ring. Then, whoever wins the Money In The Bank ladder match (Alberto Del Rio) comes out, cashes it in, and wins the belt. Vince is still pissed at Cena for losing the belt, so Cena gets "fired" (takes time off to rest for wrestlemania).
Sounds logical... right?
