The Taken King:

The Taken King will be revolved around Oryx who is Crota's father. Eres and Rahool have already mentioned the name so it seems that there are already elements in the game setting up for this. Most is mere speculation at this point, but it's apparent that the next raid will in fact be a part of new DLC that will cost extra money. Note that the raid will not be the ONLY content included in the new DLC.
More to be revealed next week at E3 according to Kotaku reports on Bungie.
