There’s sooooo many other things to worry about than an expansion to HTTYD anytime in the next decade. There’s more space at Epic for other things in the other lands, room for new land or lands, IOA needs LC replaced. Simpsons will get replaced, eventually Toon Lagoon will be on the chopping block (I’d imagine), Supercharge replacement, Volcano Bay expansion, HTTYD doesn’t need anything else imo. I say this without experiencing the land yet, obviously.
Make Luigi’s Mansion very high capacity and longer ride than the others, give us some more dining and that’d really help Nintendo.
Obviously, another Potter E Ticket wouldn’t hurt for capacity either.
