As much as I like the sets this time around, I was kinda thinking of avoiding the HP releases (pure financial reasons) but, having seen this one, I'm very seriously re-considering that position. Although they don't cover *everything* in the HP world, this year's sets now actually provide *most* of the key scenes from the stories: Hogwarts Castle, Hogwarts Express, Hagrid's Hut and Diagon Alley feature in all the books and The Burrow is in all of the later books - and the sets include minifigs for pretty much all the essential major characters too (and for everyone else, there's always Bricklink!).
Obviously, if I get these now then they can go into storage for my kids to play with when they're bigger and ready for standard Lego rather than Duplo - and once they're old enough to appreciate the HP books too...
I wonder if my wife will go for that...?!
