It's been known for months now and you can even find the new armors and even weapons in the coding of the game now (wasn't there before the 1-2gb update, but they are now). However while there are parts of the map not meant to be accessed and all the missions can be seen with a glitch...none of the new missions exists. Not to mention if this were Disc Locked Content as some people wish it was, why hasn't there been any gameplay of the missions. Looking at the old video, Crota's end was supposed to be starting at 28 and that wasn't the case either so again moot point to say that is the mission. Who's to even say that area existed before the update as well? I never saw a video of someone accessing the abyss or the rest of the Crota's End. Now there is always the argument that "There are areas that existed in the beta that still had these enemies", but that is the thing. People seem to think that placing enemies or removing them is like forge from the Halo series where you just drag and drop things and that is it. It's not that simple. To remove an enemy they would have to First remove the enemy's figure itself, then remove any kind of date to related to it (normal walking/running paths, attack/damage data, being show or hidden on the radar, spawn timing, etc.) and it's honest not as simple as highlighting and deleting the code. If you remove any one thing in the game you have to reconfigure everything else because lines of code are not universal. It would actually have taken a good amount of time to remove the enemies from king's watch and that is why they are probably still there it was probably meant to be an area in patrol during the full release. As it is however, no enemy data exist in areas that wouldn't have a mission outside of DLC. There is also no scripting for voices, to open doorways to the areas or to continue them on in some form or fashion and as it is right now just exist as pretty much the bare bones that will have gameplay added later for the muscle and skins of the area.
