Also, the rules compendium includes most of the updated "rules". For stuff pertaining to specific characters (like powers for wizards, sneak attack, etc) those are in Heros of the Fallen Lands. And, that book does have stuff in it that existing players might want that isn't errata OR for a new build. Just like someone might want Player's Handbook 3 just for some of the feats ... so too people may want some of the new powers or feats from the book even if they aren't using any of the Essential builds for characters.
