And? The files that control the weather, envirionmental effects and backdrops are't exactly part of those that are usually datamined, and those are enough to set the stage for a final event.

They don't even need any new mob, as they have everything they need: Imperial troops, centurions, magitek, alliance troops, and a crapton of monsters.

if you check the trailer that shows the final moments of Eorzea, there's nothing in it that isn't already part of the game's data.

All they need to make an in-game event is already in the game, so I don't see any indication on how the event will be or on it's existance in the fact we'll have a patch or not.
