I think it was postponed as Univeral brought forward the new park to 2023 and therefore with Hagrids in 2019 they decided they didn't need a new attraction in both parks in the same year so postponed the stunt show for a year. They are still opening one new attraction every year!Well we can only hope that, that is one heck of a stunt show, considering it has taken over two years to get something
new into that space, and they cancelled the other stunt show they had last year.
Again, I was speaking about the coasters and just felt it would be better, from a marketing standpoint, to be able to
open a new coaster, before Disney opens their next two.
