If theres going to be a second gate, don't you think DA will be there for the HE effect? Or are you saying they will split up the current park for a 2nd gate?
If there is a 2nd gate, I would want them to put Diagon in it, 2 themed lands is too much for 1 park. I didn't think too hard into this list, I just wanted to plug the 2023 gap with something. Maybe something new could fill that gap.
