hogwarts wont be open because undoubtly, hermonie and ron will join harry and theres no way ms. weasly would let ron go instead of school.
EDIT: now for a more thoughtout post after reading all your responses.
like the rest of you i'm happy harry finally got laid.
Dumbledore's death was pretty shocking but i knew from the moment they went to the cave he was going to die. Before the 6th book came out rowling said "i promise 1 of the main characters wont survive" i thought this meant ron, but it was dumbledore.
-snapes duelling abilities are badass though the visual they give of him in the movies sucks. (he repelled every single one of harry's attacks with a flick of his wand)
-Throughout the book i always figured Voldermart was the half blooded prince, think about it he's a halfblood, and his father was pretty much nobility.
-and the avada keradva (i cant spell these spells) question mentioned by some1 up there, bellatrix lestrange explained that with unforgiveable spells you have to set out your brain and heart into that spell, wanting it to hit with all your energy, it seems to not be a simple task to use one, i doubt malfoy's would've been too successful considering harry's been under it before and gained control (book 4) considering he must have little experience in doing it.
the books overall story was good, but it was only saved by the last part. throughout the book, the ron-hermonie jealousy hatred thing was extremely blown out of proportion. They have a fight in almost every book. The Romilda Vane or whoever's obsession with harry and ron eating the love potion was extremely funny, but really had nothing to do with the book. Harry getting the elves to help him was genius, except that part where he couldnt get into the room of requirement was pretty gay.
heres some questions i have i wonder if any of you can answer it:
-if the 6th years are able to almost master silent spells, why cant death eaters do it?
-the time it takes for the death eaters to say crucio somehow the others get "perfectlos tenclotus" out or something of the sort (the 1 that makes their body stiff)?
-did dumbledore ever say which house he belonged to? (i remember hufflepuff or gryffendor?
-how would voldermart have gotten his horcrux (the 1 in the cave)? dumbledore said it needed 2 people and voldermart would never let his deatheaters know about them, yet he cant do it alone.
