Here’s what PWinsider are saying on it:
As you saw with the finish of last night’s WWE Friday Night Smackdown, unless there is yet another major change in plans, Cody Rhodes will not be “finishing the story” at Wrestlemania 40 in Philadelphia, PA.
Numerous WWE sources have concurred that the decision to go with The Rock vs. Roman Reigns Mania weekend, expected to be officially announced this Thursday in Las Vegas for the Philly event, was a push by The Rock to move into the Mania main event, backed by top TKO Group Holding execs.
While WWE had been expertly building to a Cody Rhodes vs. Roman Reigns rematch, some sources believe it was done by Johnson to, as one source stated, “save Wrestlemania” after CM Punk and Brock Lesnar, for very different reasons, were taken off the board from the biggest weekend of the year.
Others believe that Rock pushed for the move and likely would have no matter what, given his massive $30 million stock payday is, in part, contingent on him hitting certain milestones. Sources familiar with the situation believe one of those milestones was Johnson returning to the ring this year and that Johnson pushed for the match to happen sooner than later with the idea he felt Reigns vs. The Rock was the far bigger attraction for the company,
So, it’s very possible that no matter who was injured or not, Cody vs. Reigns would not have taken place because The Rock was back in the game and the most important members of company management were going to acquiesce to Dwayne Johnson’s ideas.
With Johnson’s power as a member of the TKO Board of Directors, his Hollywood standing and the backing of Ari Emanuel, Nick Khan and others, the decision was made to go with Rock vs. Reigns as the headline bout, believing it would be a greater attraction for the mainstream and also help push some positive momentum for the company.
One source compared it to Johnson’s attempts to take over the overall creative for the DC film franchise, noting that he came in originally as an actor to portray Black Adam, but by the time that process was done, had changed the original trajectory for the plans from playing the opposition for Shazam!, instead pushing that Adam should have his own film so he could eventually be set up to face Superman instead and even went over the heads of executives to their superiors to get ideas approved. Johnson’s long-game was to gain control of the entire DC film franchise, only to lose that attempt when Warner Bros. Discovery gave that power instead to James Gunn and Peter Saffron.
But, in WWE, there isn’t going to be anyone that’s not going to at least consider Dwayne Johnson’s ideas. He's The Rock and has a big history of selling tickets and merchandise and movies and at the end of the day, Wrestlemania is about spectacle and The Rock equals spectacle.
PWInsider.com is told this wasn’t done to target and politic Cody out of his main event out of malice, but out of the belief that Johnson was the best idea to make money now and respect his new position with the company’s parent company. This was a strategic move to give Johnson more political power overall and to show Endeavor’s faith in his involvement and that even Paul Levesque, who has done an admirable job as the Chief Creative Officer, would "lose that power struggle with Johnson at this point", as one source surmised.
One source confirmed to PWInsider.com that former Senior Vice President of Development at Johnson’s Seven Bucks Productions, Brian Gewirtz will be in the mix as the voice representing Johnson in the WWE Creative process going forward. There are some who believe Gewirtz, who at one point was one of the longest tenured WWE Head Writers, will be around physically at least for major shows going forward, could even be there as a “Plan B” if Endeavor ever needs to pivot WWE's direction and go with a Johnson-backed creative team down the line.
Fightful meanwhile are saying that The Rock had not only pushed to face Roman Reigns at Mania, but some thought he was even pushing to win the match.
