As noted, there have been a number of creative meetings in the past week regarding booking the card for WrestleMania XXX. At this point, the only match that is considered a lock is John Cena vs. Bray Wyatt.
According to one source, there is a lot of back-and-forth discussion regarding Brock Lesnar's match on the show. The original plan was for Lesnar to face The Undertaker, however some are of the belief that there is something to the tease between Lesnar and Batista on RAW recently.
Additionally, there is a lot of talk about how to use Daniel Bryan on the show. Originally, Bryan was to work with Sheamus at WrestleMania. After the crowd hijacking at the Royal Rumble, there continues to be talk of featuring Bryan in the WWE World Heavyweight Championship match.
