What do you guys think SE will implement for future content that's used to obtain "end game" gear (or considered end game, such as Darklight, Relic Weapons, etc) aside from what is currently known, such as Labyrinth of Bahamut, Dungeon Raids, Primals, and the Relic Quest itself? (I'm assuming FATE events won't shell out that kind of stuff)

Basically, what guesses do you have at other types of content, and in turn, the methods SE might use in conjunction with said content to obtain high-end gear?
