I don't disagree with you. I'd LOVE answers.

But it's like Tom Bombadil. Tolkien refused to ever explain who or what he is. As a result, he's still a widely debated character. Is he Illuvatar? Is he the spirit of the world? Is he the essence of good?

Now, what would have happened if he'd told people who Tom was? Result? No further discussion.

By not telling us anything, it drives us fans crazy, and we just can't stop talking about everything we want. The topics and discussions keep going, and the more they keep going, the more new people are likely to read them and want to get involved. It keeps the discussions alive as all of us crazy fans wait eagerly for the next PFH for them to reveal just a small portion of what they're doing.

And, yeah. I imagine they're eating it up.
