Since we saw the Mirror Aqua boss battle in 0.2, I was starting to get a bit worried that it could use Hunter of the Dark as its theme, as with the Devil's Wave Heartless battle. Could Square really be this lazy or are they thinking of using other tracks from the series in 0.2, especially in the battle with Mirror Aqua?

Id like to think that Hunter in the dark was a place holder but who knows

I highly doubt that Yoko's remastered soundtracks are going to be limited to Kingdom Hearts X back Cover. 0.2 will definitely have some remastered tracks (sure, it wasn't present in the demo but they were probably placeholders to begin with).
