Even though it's slightly spoilers...Follow

But since it's optional content anyway - Looks like if it's not through the Mogstation, we're getting a lot of FFV and VI themed items and minions, like Relm.

It'll probably be through Lords of Verminion (or main storyline but we only got one true VI reference in the story unless you count the fact the dragonsong war and war of the magi are technically references.)
