Something I find interesting is that going forward, the "Constant" IP that is going to be present for all of the HHN's, is Universal Monsters.
Osaka will be beginning to use them in the House format this year, with what seems to be a transplant/version of Orlando's Universal Monsters from 2019, Singapore tested Universal Monsters last year with the Sting Alley Pop-Up Experience, and Hollywood and Orlando are now fully going all out in Cross-collaborative stories.
Add in Dark Universe for Epic Universe, and the Fab 5 of Horror be shining bright at Universal Parks and Resorts.
