Go on this video and starting at 4:48 we see a brand new location on Earth. (From what I can tell.) Then shortly after a new crucible map on one of Mars' moons and something like a dragons skeleton (Rib cage) on a place on what I can guess to be the Moon. I call this DLC because they showed the footage after mentioning the 2 dlc packs and how they'll expand Destiny. It seems to be from before the golden age (more present day) and i'm pumped.
Edit: We can see a flag and banner on the left that might tell us something about the location.

That area has been known for a while, or at least a picture of that area has. You also forgot to mention that right after that, they showed off A Crucible map on Phobos, like I did 50 mins ago :)
