I know about all the "secret" areas, it's all shit being worked on, I'm sure some of it was finished pre-release, but that's the way the video game business operates now a days, just because there are fully mapped out areas that you can access in no way means they are on you disc, this game is run off of bungie's servers, most of the content is on those servers, not on your disc, again, not that hard to understand.
