The owner of Otherworld Miniatures has retired and the figures have or will be sold to other companies. There won’t be any new Otherworld sculpts.
I’ve not seen any details about who’s buying yet. However, as Crooked Dice and Dragon Bait have previously taken on old Otherworld figures, you might want to keep an eye on them.
I doubt that whoever takes the ranges on will have such a strong focus on old school AD&D.
