Inception stunt show would be radical. WB tried to get Nolan back by giving him the money they owed him for Tenet, I could see them trying to at least keep their Nolan films in the public spotlight.
But on topic I have a feeling the replacement will be something alot more grand. The studio tour is awesome but the ending really leaves a lot to be desired. Sorry but Nope is so much more underwhelming as the end of the studio tour than Supercharged ever was. Universal has been shifting away from having a giant screen be the main part of the ride so I'm pretty sure it's going to be something more akin to Earthquake. Wicked and BTTF I don't see happening at all, Universal would want to save those for something bigger... probably in Orlando because they get everything.
