You're gonna be bothered by how cool I am.

Isn't it possible that when Jo said "Now we know", she was referring to the books from Harry's POV, and what he "knows"?

The way she put that in the MN/TLC interview seems to suggest that she was speaking from the book's POV, or to what the sixth book suggests about Ron and Hermione, (which is from Harry's point of view and what he thinks about Ron and Hermione) which is that they love one another and will get together soon.

But Harry's POV about Ron and Hermione could be wrong, just as he's been wrong about countless other assumptions before, misleading us as the reader as well. After all, the fact that neither Ron or Hermione have made any movement in six years towards getting together, and the fact that neither have said anything whatsoever to Harry to confirm his suspicions about their feelings for one another looks mighty fishy.

I think though it's very possible that the shipping question is truly over, there is still some question about whether Rowling was speaking about us knowing it's Ron and Hermione from her telling us, or us "knowing" it's Ron and Hermione from our reading of the sixth book.

If this is the case, then indeed, everything could be turned on it's ear in the seventh book. R/Hr has always looked fishy to me because of the lack of admission for six years from either party to Harry or anyone else that they have feelings for one another, and the lack of any progress on either Ron or Hermione's part to finally admit "feelings" for one another. And the mere fact that when something happens that should make them admit feelings if there are any, all that happens is that they begin behaving more "civilized" towards one another. It just makes no sense if they really are crazy in love with one another.

If there is no question to R/Hr, then why hasn't Harry ever gotten a confirmation yet from either one, or someone else, that R and Hr like one another?

Not even Ron's own family, Ginny or the twins, make any jokes about his supposed feelings for Hermione... no one thinks anything about it... and if the Weasley twins will rib Ginny about her feelings and boyfriends, why wouldn't they do it to Ron, whose feelings about Hermione should be "so obvious", and who they have always picked on for anything they could find to pick on him for?

Too much does not add up, and too much DOES add up to that Harry is going to find out that he's been wrong all along about Ron and Hermione's feelings... in which case, all of Hermione's actions towards Harry, and the reactions from Krum and Cho toward Harry and Hermione, will quickly add up to that she's been in love with him all along, and he will finally find that out.

I believe that Rowling always speaks about the books with the information that we already think we have from them. She gives us nothing new, only what we've already read and think we know. And what we know is most often what Harry knows.. or thinks he knows by the book's end. As Rowling has said that book six seems one half of a larger book made up of six and seven (which is the first time that one book "skids off" into another, as she herself said), then we can be safely certain that reveals and twists and turns are coming in book seven, which were set up with red-herrings and misunderstandings from book six. Whether or not Harry, and consequently WE are wrong about what we assume from book six, always remains to be seen in the next book.

Again, Rowling was speaking only about what we "know" from book six... which is what Harry thinks he knows. When speaking about specific plot points in her interviews, she always just reiterates what we already "know" from the books, and nothing more. Rowling is not going to let slip what in book six is going to be revealed as a red-herring or a twist in book seven.

I think we should all remember that.
