Is the Shadowbringers theme song not getting released this time?

[Enkidoh]

There is a theme..its the one we hear in the trailer

That's not the 'theme song' though but just the trailer theme, I'm talking about the vocal song that SE releases as the actual 'main theme' for the game/expansion (namely, Answers, Dragonsong and Revolutions for FFXIV 1.0/ARR, HW and SB respectively). With the previous expansions SE released the upcoming theme song a month or two before the expansion's launch with a trailer video sneek peeking various story cutscenes from the upcoming expansion main scenario, and they were always identified with the subtitle 'Main theme of <insert expansion title here>'.

The fact Shadowbringers does not is unusual, although as I mentioned not surprising given Uematsu (who composed the earlier main theme songs) is retired on medical grounds for the forseeable future, although Soken would definetely be a competent replacement he's probably too busy with the expansion's sound direction in addition to music production to also have to compose, direct and oversee the performance and recording of a complex orchestrated vocal song as well.

Either way it's unfortunate SBS has no dedicated vocal main theme song, but as a fan of FF music I have to say that Uematsu's health is far more important.
