Mattel released the three lead characters as dolls around the time of the movies, all in the same size as Stacie and friends, but with articulated arms and legs, so new dates.
Hogwart's Heroes are wearing their wizard robes and the kids have head sculpts made in the likeness of the actors/movie characters.
Magical Powers had some "magical" features. They both have a magnet in their hand and a lever in back to move that same arm. Hermione is MIA right now, but her accessories have light up features etc.
Wizard's Sweets are Harry and Hermione in casual christmas wear as they visit Hogsmeade.
Magical Talking Hermione was a separate set (as far as I know) where a bracelet helped her say some of her movie lines. Don't have her.
