Yeah, since they're not putting classic remixes into the main game, I think a DLC would be a good way to cater to fans. Something that's outside of the normal game, and can be bought and funded separately from the original soundtrack. Or remember those "CD" tracks you could "find" in Dracula X Chronicles or Order of Ecclesia? Some of those had original 8-bit songs you could play in the background. They could do that too, something to "find" like the Bestiary pages if they don't want to dwell too much on RPG items. But yeah, I doubt it, so it'll just be a hope and dream.
