Where are we headed in #6?

The fourth book ended with Dumbledore doling out assignments for 
various characters, which (happily) gave us an idea of where we might 
be headed in the fifth.  Is there anything this solid in OoP that 
shows us what might be in store for us in the next book?

Right now I don't have a specific passage to point to in OoP that 
makes me say, "Aha, this means such and such is happening next!"  But 
I do have one hope and one fear about book six.

The fear first:  I'm afraid Harry is going to feel even more 
alienated in book six, and he's going to try his best to distance 
himself from everyone.  Maybe it won't happen this way, but I'm 
afraid we are going to see an even angrier Angry!Harry next time 
around.  Hopefully someone can snap him out of it before book 7 (I'm 
pulling for Ginny to fill this role).

Now the hope:  I hope the Mystery/Action/Danger is more Hogwarts 
centered in book 6.  I hope Voldemort needs something from Hogwarts, 
or something along those lines.  It doesn't have to be a repeat of 
the Sorcerer's Stone-as-quest-object, but I won't mind if it was 
similar.  If the mystery/action/danger is at Hogwarts, maybe it will 
help take the edge off Harry's feeling that he is being left out of 
the loop on everything important.
