There's room around the park for them to add a tent for another house somewhere backstage. UC is most certainly not beholden to HHN. They aren't replacing Shrek right now because they're focusing on building a brand new park and spending a lot of money doing it.The only reason I can see for keeping Shrek is to have a space for an HHN house. Last time I did it was 2016. Shrek is a fairly large property that deserves a lot more than an old 3D show.
