Of all the big, free updates that Nintendo has released for Animal Crossing: New Horizons thus far, this upcoming Winter one might have the best mix of new content and quality of life updates yet. Launching on Nov. 19, the next New Horizons update won't just add seasonal events for the holidays—it also adds in a much needed save data transfer option, new hairstyles, "hip" reactions, and even a way to expand your home item inventory.
The save data swap to a new Switch can work one of two ways, and it may finally help resolve things for households that started out together on one system and one island. To move an entire save file with the island, player residents, animal neighbors, and all the rest to another Switch, it sounds like users will need to download a free Island Transfer tool from the Switch eShop. The other option is to just move a single resident's data to a new Switch; in this case, they can't be the island's resident representative (i.e. the player that makes all the top-level decisions with Tom Nook). For a resident move, Nintendo says "the resident, the resident's home, and most items held by the resident and kept in storage will be transferred to a new item on the new Nintendo Switch system).
You'll have a week after the update launches to do whatever data swaps you need before Turkey Day rolls around on Nov. 26. On that day, Chef Franklin will show up in the plaza and ask for special ingredients to cook a feast for all the island's inhabitants.
Then, come Dec. 24, there's Toy Day. As always, Jingle the reindeer will come to town bearing a sack of gifts—players can then choose to help Jingle deliver presents to all the animal neighbors.
Save data transfers and new holiday events are all well and good, but I have a feeling the most diehard New Horizons players are probably going to be more excited about the remaining additions. Six new hairstyles and nine new reactions will be added to the Nook Miles kiosk, finally letting players sport an afro (or go bald) and plop down for a sit next to their favorite neighbor. On top of that, a chat with Nook will give players the option of bumping up their house inventory cap from 1,600 items to 2,400. That upgrade presumably comes at a price, but I'm sure that any intrepid furniture traders who're in danger of hitting that 1,600 cap are probably able to pay it.
Nintendo's still not done with the seasonal updates, either. There's another free one scheduled after this for late January, 2021. As for whether we'll see the support continue on past New Horizons' one-year anniversary in March, time will tell.
