As noted earlier here on the website, Lesnar has signed on for a minimum of two appearances per month over the next year plus additional appearances during the build to WrestleMania 29. The belief is that Lesnar will make around 30-35 appearances over the next year but WWE likely has the ability to negotiate additional appearances, if he’s willing to make them.
As seen on RAW, The Rock teased a run with the WWE Title. Speculation is that Lesnar will eventually challenge The Rock for the WWE Title at WrestleMania 29. The tagline for the event would be "Rock vs. Brock".
Speaking of Lesnar, he was not at WrestleMania, the WWE hotel or any WWE related events in Miami over the weekend. WWE tried hard to keep the deal a huge secret.
