I've seen two of the dolls in the last month- a Taeyang Magna that I bought, and one other Dal that has been there since pre-Thanksgiving Day. (She has short blonde curly hair, gonna try to find her name in a sec). There was also one of those mini-dolls that come in a book-like case (her name is Lupinus, IIRC), but i havent seen any other ones appear since then.
They are still at stores, but I guess we are in a dry season as far as them showing up.
Edit : the Dal I saw at my TM is named Colline.
