Wow, I'm still baffled that areas that where in the Beta/Alpha are not part of the final game. That parts of the UI already exist in the game doesn't surprise me. But entire pieces of the DLC.... Ahh wait a moment, you meant DLC as in Disk Locked Content instead of Down Loadable Content.
Rewatching the vidocs makes Destiny look like completely different game than what we got. Also what happened to Saturn? It was mentioned as playable in one of those vidocs.
Don't forget this as well:
