At least HTTYD is a 1st party IP. They won't care how it's doing as a franchise if they don't have to pay for it.
Universal is going to want to use as many 1st party IPs as possible. FW is already assumed to be half 3rd party (Nintendo + FB, with DW and CM being 1st), and I'm betting Universal is not super happy about that fact.
I expect them to really push for 1st party IPs even harder in the future. So this is why my second land I am predicting for dry park 4 in 2033 is.....
F&F-Supercharged-LAND. (I'm half serious.)
Maybe it's my lack of imagination, but I'm just not picturing this. Wouldn't guests have to walk a very far distance along a narrow path to get anywhere?
