I'm pretty certain Dumbledore's dead. JKR said somebody'd die in Book 6, nobody else did. Plus, she definately confirmed it in interviews. "The old white wizard must always fall."
I'm reminded of how so many people kept saying that Sirius wasn't dead after book 5 came out, even though, again, nobody else died and JKR said somebody was gonna die. Delusional people.
I actually thought that the Ron/Hermy thing was obvious since Book 4. Ron just didn't realize how he felt.
And as for Harry being a whiney snot, yeah, but then he has to deal with so much crap I can't blame him. I mean, honestly, the reason why I didn't like book 5 much was because it was just one moment of Umbridge-related injustice after another. I'd be pissed, too. Plus, hormones--that's how most teenagers are, or really how most people who are constantly bombared with unhappy things are. Give the poor guy a break.
