Well, I can't blame them--if they sell? And they're exclusives, so fewer are being made. Honestly, there's like four different Harry Potter dolls (regular! weekend clothes! Yule Ball! tournament!), three different Rons and Hermiones--dolls with variant outfits aren't unusual for them, particularly for a property that popular. Even with Golden Compass, there's several Mrs. Coulter dolls and/or outfits, and two separate Lyras.
