I do wonder if this project is being used as a safety net for the future. Minion mayhem is relatively new but the theater and ride system date all the way back to Hana-Barbara just with a new coat of paint. It would make sense if they were putting in a new despicable me attraction so that the IP will be kept in the park when the old simulator inevitably runs out of its service life. Minion mayhem seems decently popular but it’s not one of their star attractions, so when it begins to have age-related issues I’d be surprised to see any mummy-style refurb to keep it going. They might be doing this new minions attraction so that when it comes time to replace minion mayhem, they can start fresh with a new IP while still milking despicable me’s popularity somewhere else. But that’s just my take on it
