or maybe they thought "you know what? this content doesn't mesh well with the first chapter of the story, but we need this part of the content primed and ready for the DLC, so we will develop the transitioning into the current content so there is no hickups on expansion launch" Not sure if you played WoW, but i guess you would have felt cheated and ripped that you couldn't have expansion content, despite being able to glitch into their maps before expansion.
