1. The Idea Of Randy Orton vs. Batista
Simply put, this main event concept has absolutely no chance of happening as it currently stands. At this point, it's pretty much a financial fact that no one wants to see this particular singles match as the crown jewel of Wrestlemania XXX. It would get booed to hell, we might see a portion of the audience leave, we would definitely hear a chorus of various Daniel Bryan chants flooding the arena. Especially now that Batista has gone heel, there's simply no feasible way to sell this match as important to anybody but the most casual of wrestling fans. Randy Orton vs. Batista straight-up would be a business disaster. Something or someone needs to go into the main event in order to save it, and I can't think of any other option not named Daniel Bryan.
