I think that now my most wanted figures are new or updated versions of existing character (although I do really want Lee Jordan, Bill and Xenophilius). I really want a new Hagrid without his overcoat, the winter trio (I've seen hats in Friends and City sets that would be perfect for Ron and Hermione), wedding variants, DH Pt.II Ron, prologue Hermione, Ron and their children. Seeing what they did for Victor, I also really want an improved Mrs. Weasley (I saw a 2023 Friends hair that looked like it would work great for her) and a printed-black dress Bellatrix. Oh, and of course Narcissa! And a OOtP-style Death Eater (lots of them)! And Dobby in his shoes! Just give me all the figs!
I think we should add Alicia Spinnet and Katie Bell to the minifgures we still need, too - even without Katie's expanded role in HBP, it would be fantastic to get the full (dream) team and remember Lego gave us (and named!) Lucian Bole and Marcus Flint.
I am also desperate for a Fang, and also a pygmy puff and a better representation of Crookshanks, too. I think my most wanted set is a tent from DH -- but who knows if that will ever appear.
It's so exciting to think that this years sets could literally be from any one of the films -- the June 2022 and March 2023 waves have really set an exciting precedent! I'm currently re-reading the books and I love thinking about all the things Lego could cover next.
I must admit that I share your sentiment, but these films are so hugely popular and profitable so there's clearly an audience for them! I really like Spider-Man and Batman (mainly in their video game and comic book forms) but the Marvel multiverse does nothing for me. But with Lego, there's room for everyone!
