This one is also looking like a certainty to happen. The build started for it on the Raw after WrestleMania, with Seth Rollins running away from Brock Lesnar. The Beast is now set to come back for revenge, and of course the WWE Title rematch that he is owed. It is a natural narrative to run, and it should also be one hell of a match. The bout seems even more likely after Paul Heyman put Lesnar and Rollins in the same sentence, when talking about feuds on the WWE Network Steve Austin show. The big question is how WWE will book the match. They don't want to dampen Lesnar's star persona, but there's also the fact that Rollins has been doing so well in his current position.
