So, since we were whisked away to some void-like stasis, that opens the possibility of Gilgamesh making himself known. He travels the void to various Final Fantasy Worlds, so it stands to reason he'll use the void to come to Hydaelyn.

Would be be a Primal?

Would he be the boss of a new dungeon (Void Dungeon maybe)?

Would he be summon-able?

Would he be an NPC?

What do you think? Should he show himself in 2.0? If so, what part would you want him to play?

P.S. Even if where we were sent wasn't "The Void" it obviously exists in Hydaelyn in some way: voidsent and Atomos used it.
