Back cover of the Bloomsbury children’s edition of Half-Blood Prince released, includes cover copy; new information revealed. Could be considered spoilery. There’s a ton of other stuff, including the entire cover of the Scholastic deluxe edition, so I’m just going to refer Potterheads to The Leaky Cauldron and The Daily Snitch. There are (what is assumed to be) actual, concrete spoilers out on the internet, so tread carefully.
