US Version UK Children's Version UK Adult Version Smaller Versions of the UK ones if you don't want to wait for the big image to load Aaaaand, smaller wrap-around version of the UK children's copy Except for a certain amount of joy over the fact that Ginny Sue is in fact not present on either that I can tell. :) Of course, Draco's not either, but, eh. Although the fact that Salazar's locket is featured on the adult UK cover makes me kinda happy because the last adult cover featured the HBP's book, which was pretty much key to the whole story. I think it's kinda cute and appropriate, actually, that the final kid's cover be Harry, Ron and Hermione on their one last adventure together, even if they all do look like complete goofballs.
ETA: Alright, all that was written before I could see the UK covers in hi-res. Now that I can see the kid's UK cover for real, I'm gettting a house elf (I think) holding maybe the Sword of Gryffindor (I bet it's Dobby...shoot me now, I think he's the only character I hate more than Hagrid), what looks like it's probably Slytherin's armor (although the rubies on the helmet suggest Gryffindor...), Hufflepuff's goblet(?), Harry's Patronus to one side and a snake in a crystal ball to the other. Also, Hermione in purple robes and Ron in Draco's green robes, although I'm not really sure what that would mean.
I vaguely wonder whether the curtains are supposed to suggest they're fighting 'beyond the veil' on the US cover, especially since there seem to be all those people in the background. Also, the fact that there's an actual arena sort of amuses me, most likely for DTC reasons. I have no idea what Harry seems to be calling on, though, Voldemort doesn't seem to be doing the same thing, mostly just leaning back away from Harry. Hmmm...
...yeah, I'm mostly just confused. Thoughts?
ETA: HArry appears to be wearing Salazar's locket on the US cover. And has no scar. And his eyes appear blue...
