I see Chavo "accidentally" costing Rey the match somehow, hopefully slow-building a turn.
If Khali is taken off, they can have Boogeyman make a cameo, perform some voodoo, and manifest Khali's soul in the Big Show so that The Undertaker can still get his revenge. And the ECW Champion stays strong because he wasn't in his right mind.
Finlay/Regal and the tag title match will steal the show.
