All done with Deathly Hallows. I was glad to see that the spoilers that were posted very early on by the supposed hackers were wrong.
I was also impressed by the accuracy of some of the hypotheses I read prior to the books release. Or perhaps they are self-fulfilling. Maybe Rowling read some too and thought "now that a way out of that I hadn't considered." That would be kind of cool and disappointing at the same time. I don't think that happened.
