It does not reveal anything that we did not know from the last book but the cover is interesting. We can assume that it is Harry, Ron and Hermione on the cover. It seems that they are in some sort of treasury or something. Also it appears that Ron is wielding Griffendor's sword. To the far right, the stag I assume is Harry's Patronus, while to the far left the entangled serpent in the orb is mysterious. It is perhaps part of Slytherin's necklace that Voldermort's mother sold? Also it looks like the gang is running/jumping/leaping away from something and they had already suffered some wounds.

Anyways, what do you guys think?
