But it's also a not-so-subtle homage to Disney's parks: Sleeping Beauty's Castle, the centerpiece of Disneyland and Disneyworld, is replaced by WarCraft's Stormwind Keep, while the lake with Darkmoon Ferris Wheel clearly resembles the waterfront section of Disney's California Adventure. Heck, all the attraction posters around the map imitate the modern 50s-era look of those that still line Disney's parks.

There's more than just a map in this update. Players get 100 new cosmetic items to find in loot boxes. 17 of those are new skins: Some are homages themselves to characters in other Blizzard games, like Barbarian Zarya or Nova Widowmaker, while others are from Overwatch short animations, like Crusader Reinhardt or Ecopoint: Antarctica Mei. The other 83 are standard loot box fare, from emotes to highlight intros to sprays. Note that these are additions to the core cosmetics pool, meaning they aren't event-bound and can be earned year-round.
