Judging from what has been said by people who seem to have some insider info, most of the interiors and the ride is complete. Meaning what's left is mainly finishing prep for prefab and then installing prefab, and getting those moving outdoor pieces running. This happened in Japan pretty quickly is my understanding, so I don't think they'd need 14-16 months. I could be wrong, but I feel like it's gonna be open by Spring by the latest. Any longer seems to me to be a bad move considering the poor attendance this park is getting.
Also, I can see from the email notification what you said before editing, not sure why you had to be kinda rude there originally
EDIT: Spring 2023 by the latest
