PWInsider reports that Brock Lesnar 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.
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.
WWE's website posted an article last night looking at why Brock Lesnar has returned. They noted that Cena and Lesnar have history, writing, "In early 2003, when Cena was first trying to climb the Superstar ranks, he sought Lesnar's WWE Championship and even mocked his finishing maneuver – the very move that crushed him on Monday night. Is Lesnar back to prove a point to Cena? Or is he just on an uncontrollable rampage? Only one thing seems certain right now: Brock Lesnar has rocked WWE once again … and he sure looks hungry for pain."
