There are definitely areas that are not open to the general Beta public at the moment. Just like with the Iron Banner Crucible opening up that door past the character Vaults temporarily; I think there are places they have sealed off until final release. Like the Door across from the Voice of the Traveler's central area. Or has anyone ventured down into the sub level under the ship hangar? Where you can buy new speeders and spaceships? It is completely empty aside from a few seating areas and NPCS you can't interact with. There's someone putting together robots/Exo's and even farther in there appears to be a counter with a digital display on the inside where a vendor might stand for...I don't know....weapon/armor customization/upgrades? Let's not forget the four or five doors around Russia we can't breach (unless you abuse the die/revive through the wall glitch)....and that's just one part of Earth. I'm very excited :)
