- New concept art for Cars & Villains, plus concept art showing both areas together plus next to already existing land, hopefully even a model
- Limited addition Tron: ARES promotion at TL
EPC: - Something new. Who knows if it's COCO, new Figment, or new SSE. But just something new-ish ride wise
HS: - Monsters Inc land updates
- Muppets Coaster major updates, concept art, details, music, etc
- AC updates (Including Bluey show and or meet and greet)
AK: - Zootopia opening date
- Details on TA, play area, ride systems, more concept art, etc
- Drone/water nighttime show
- Limited Edition FIRE AND ASH promotion
