Hello, i'm new here.
Thought I'd throw my cmf predictions into the mix.
1. Ron Weasley in quidditch gear (Broom, new quaffle piece)
2. Hermione Granger in winter clothes ( wand, book/mug)
3. Rita Skeeter ( quill, paper)
4. Gilderoy Lockhart (pixie, wand)
5. Sirius, OotP version (padfoot new piece)
6. Madam Pomfrey ( bottle of skele-grow)
7. Ginny variant ( either quiditch outfit or CoS variant with Tom Riddle's undamaged diary)
Obviously, there are many other possible figures, but these are my best guesses.
