> Are fiction books really that updated (in terms of the words, not formatting)?
Sometimes, but not often enough, in the way that's under discussion, that it's a fair comparison to what's already done in the film world, I think. There are a few famous examples (The Hobbit having a scene significantly modified to better fit the LOTR, for example) but major modifications to different releases, for reasons other than censorship (which strikes film and books alike), aren't as common as in film, I'd say.
