So this proves that there is an area there, that we will be able to travel to it via the Director, that it has a designated place on the map, and that a glitch exists which allows us to see these icons ahead of time. So there's some areas that at least partially exist which we can't yet enter without glitching our asses off... How exactly do a bunch of destination icons prove that content is not only complete, balanced, and ready to go, but also already on the disc (versus Bungie servers or even anywhere)?
