The coaster point is well met, I am just used to Orlando that has had a streak of coasters, so didn’t realize it has been a long while for DLR.
But this attraction is akin to Uni’s Spider-Man or Transformers. Which is fairly complimentary and non redundant with DCA’s lineup. If the water ride is true for Avatar, that’s actually pretty good variety. Ya they are both going to be a mix of screen and practical, but they are very different feeling experiences and neither feel remotely like soaring or guardians.
For Classic dark rides, we’ll see which of Frozen, Coco, Encanto and Zootopia bubble to the top.
I don’t think any coasters are in consideration for DLR right now, strangely. Tomorrowland redo sounds 7-8 steps down in their priority list these days.
It’s also worth mentioning again this is an HK co-development, and HK doesn’t need a coaster next to Space. It needs a blow-out partially screen mediumed attraction, like Spider-Man.
