Re: Which match should main event Wrestlemania 30?
Two factors IMO
Which one has the WWE Championship gives it an edge and if a John Cena heel turn is planned.
A Cena heel turn against Taker, has to main-event. Rock/Brock is probably the biggest match but neither guy needs to main event and the match doesn't need the title. it would work just fine in the middle of the card.
So basically if Cena turns heel then that's the main-event if not Austin/Punk, especially if it has the title obviously.
