*Spoiler warning!!!!*
Of course I am!!

Well, I have read gazillions of forum posts on HP websites, and I have a few ideas...
First of all, the OotPhoenix's secret keeper is dead (Dumbledore), which, I think, means that none of the OotP members will know where grimmauld place is, and they will not be able to find it. Harry found it in book five, because it was the note from Dumbledore that he'd read, and gotten the information on how to find the place, from.
Second: I know the majority of people believe that Snape is actually good. hey say that Snape killed DUmbledore on Dumbledore's orders. This does make some sense in this way (This below theory by myself, from others'):
Dumbledore could have previosuly discussed with Snape that, if anything were to happen (Let's say Snape told DD about malfoy and the unbreakeable vow), that DD would ac, and wait for Snape to arrive. Then, SNape would be able to finish malfoy's job for him, and Malfoy would still live. DD spoke to Malfoy about how he was not really a killer... and Malfoy was about to decline, it appears, wen Snape came.
Third: This is my own theory. I have not seen anything about it elsewhere, so I am very interested to hear what you all think. Because Moody is so paranoid, and not just for other's safety, but for his own, most of the time, it leads me to believe that he fears death. Maybe not of what happens after he dies, but what will happen as he does... I think he is afraid to die, in mostly anyway, under any circumstances. But after "All he's seen," and such, it would make some sense.
I do not fully believe that R.A.B. is Regulus Black. In one of the other books, the translation for Regulus Black's name is spelled different, as are the first letters of each name changed. However, the translators have translated incorrectly, too, so this is not a full promise. It could be likely, however, because Regulus Black was killed, as Sirius states in book 4.

I did hear that J. Rowling said she was not going to say anything, and still hasn't. But then again, at one time, I thought she said "Well, it's not much of a big surprise to say this, but Harry will live," kind of thing... it was almost an exact quote, I just cannot remember how she said it. But that could be fasle information floating around, too, so... we never know! Two important characters are going to die, not one, but two. I am stumped on this one... we could think of it as "One important char," so it'd have to be REALLY important, so I can only really think of Harry as a highly important character, at least for the time being, besides Snape or Ginny. However, if we broadened our horizons, and said, "Oh, well, an important character, someone who could/can teach Harry something," then here are my ideas:
Kingseley Shackelbolt (Also my idea for the person who Rowling said, "We have not yet met properly." Theer is someone we already know of, but do not know much about. I think it is either Shackelbolt, or Moody)
Lupin (I'm think the majority will go for ths, since he has been a big help in a lot of ways, and I think there is more of him to come)
Moody (Kind of the same as the above, only he hasn't done much, if anything, for Harry as an individual. But from what I have picked up, he was Dumbledore's friend, he met DD when he was going to Hogwarts, and they realized that they has some great similarities, and eventually became friends. moody trusts no one, so for him to trust Dumbledore, he must know quite a bit about him.)
Snape (I think this is so, 1.) because he IS highly relevant and important, and 2.) He has just been a huge part of, and made a big impact on, Harry's and the others' lives. What's he to do now?)
Those are some of my ideas. Tell me what you think!
