I think anyone expecting a new “land” should temper expectations. The street Minion Mayhem is on is literally already called Ilumination Ave. I took the release as UO just describing where within Production Central (as in, it’s not taking the whole area because HRRR will still exist as is) this “Minion Land” (aka, a concentration of Minion-themed venues) will be located once the walk-through and restaurant are opened. Maybe they’ll replace the Donkey meet and greet with rotating characters and that’s about all I’d expect.
