The "spoiled" thing is yet another reason it's likely to be Love or Sky and can't be Roxxi. Cornette was vein-popping over the Knockouts complaining about stuff, and that's definately not a Roxxi thing to do. She didn't even act offended in the segment. It is, however, an Love and Sky thing to do.
But that aside, since the main eventers of the Knockouts are participating, one of them is going to win. So that gives us the options of Gail, ODB, Roxxi, and to some extent Traci - all faces. And since this type of match definately isn't going to boil down to a face v/ face, a heel is going to get shaved. Love, Sky, Christy, or Jaqueline would be my bets.
