I wonder if any of the fake leaks from this year will end up in the game. Like how Eye of Azshara became a dungeon in Legion and Tides of Vengeance became the name of a patch in BfA.
Maybe they could add a gnomish or goblin contraption that's called S.O.A and the flavor text just tells you that no one can agree what the acronym stands for.
A very obscure joke for 99.9% of the player base, sure, but it would be appreciated by all of us here.
