Will The Hobbit do damage to the books?

[Glorthelion]

I've read the earlier replies. If Jackson wants to 'show more of the story' then perhaps the third film shouldn't be part of the trilogy but rather a separate film containing white council stuff, something like an interquel. That way like some people said earlier in the thread, the continuity wouldn't be interrupted.
Jackson is a talented director, I love him and I'd hate to see his huge project turn into a trilogy of error.
