Thats whats the telling point of the show, really. They could always do a segment they throw in there w/ Vince mentioning what will happen, though, I suppose. Chances are its just going to be Orton v. a mystery opponent at the ppv, which is the best way to go anyway. But they should emphasize that is what is going to happen versus being so vague about the situation.
It does make sense to wait until Friday.
