How much would it actually cost to replace only the ride system for MIB? The only purchase is the tech and the RV. The ride itself wouldn't need its AAs or facades invested in.
Considering Antarctica: Empire of the Penguin at SeaWorld was one of the first uses of the tech and the whole land, including the restaurant, facades, habitat, queue, and the ride itself, cost about 40 million USD, wouldn't a MIB refresh be maybe 15 mil USD max and possibly as little as 8 mil USD? That is honestly next to nothing with the budgets Universal normally deals with.
