Amazon: Ever-Growing Behemoth, or Topped Out?

Obviously, for book publishers the terror over the past few years is that Amazon is going to eat up everything, laying waste to the old book-buying system and forcing down the prices they can ask while at the same time everyone dumps paper books in favour of Kindles.
