As noted last week here on the website, current plans call for Triple H to defeat Brock Lesnar at the WrestleMania 29 pay-per-view. WWE officials want Lesnar to headline WrestleMania 30 against The Rock and the feeling is Lesnar shouldn't be "jobbing" at this time. This is one of the main issues WWE is currently dealing with. The plan as of right now is for WWE to do a subtle tease for Lesnar/Rock on RAW the night after WrestleMania. There may be a backstage segment of sorts and not a full blown push/confirmation for a match between the two. WWE management doesn't want to lead fans into believing the match will be taking place at SummerSlam.
WWE has plans to feature a WrestleMania Rewind edition of RAW in the near future. The plan is to do WrestleMania rematches from previous years.
