I don't think the CEO part matters much. It's his extended absence at shows that would be a turning point/transition for the company. Maybe for the better, maybe for the worse, but only time will tell whenever that transition begins.
Stephanie stepping in as interim CEO/Head of the Board makes the whole thing seem planned to keep a McMahon as CEO with Vince hoping she is a puppet that will do his bidding. I would be surprised if her stepping away wasn't in hopes of or a contrived plan to return as interim CEO once news of the settlement and/or investigation leaked.
