To those who missed it, FLOW also announced via their official Twitter that the opening theme for Tales of Zestiria the X is entitled 「風ノ唄」 (kaze no uta, Song of the Wind). The song was supposedly used in the new trailer shown during Machi Asobi last weekend, but the trailer has not yet been released publicly online.
That said, Tales of Zestiria the X will be airing July 2016 worldwide, with English subtitles provided possibly by Daisuki.net.
