Shop Disney has posted via their Site that their Exclusive Star Wars Droid Factory Advent Calendar will be available again on October 2, 2023. If you recall they released a Star Wars Droid Factory Advent Calendar last year (2022) as well.
Was kind of excited to see this in hopes it was a new Advent Calendar for 2023, but after some digging I found that Shop Disney UK is already taking preorders for this Advent Calendar and the product page is showing the exact same product photos as last year, so looks like its just another re-release.
There will also be a new 2023 Holiday Droid Factory R8-H23 Droid getting released this year as well. Not sure when it will drop yet (Maybe Oct 2?), but we will make a post if / when we see it go live.
