I am so happy to know that they will be using polyjuice potion. I was worried, although, I don't know how else they would have done it (even though they always seem to find a way how too). I wonder if they will be using the polyjuice potion correctly for all of the other parts the characters use it. I can't wait to see Hermione transform into Bellatrix, and Ron into her friend. Soooo pumped! 364 days and counting!
