LEGO has revived their Harry Potter license this year with "redos" of some of their iconic sets:
Dobby's Release
Quidditch Lesson
Hagrid's Hut
The Burrows
Hogwarts Express
Hogwarts Castle
The only one of those that's truly a new set is The Burrows, which they've made fairly true to the movie, looks like. I'll be buying that one, and if I talk myself into it, Hogwarts again. I've got the first Hogwarts Castle but passed on the additions. Now that my boys are getting into HP and LEGO, it's time to get some more toys.
