They have revealed the artist and the title of Tales of Symphonia: The Animation United World Eposide's theme song at Tales of Festival 2011. They also seem to show again the Zelos-sensei's Private Lesson just like they did the Tethe'alla arc.
The opening the song is tittled ホ・ン・ト・ウ・ソ (HO・N・TO・U・SO) by the artist Me, the same from Tales of World: Radiant Mythology 3's opening theme.
Finally they also mention the release of Volumen 1 will be sometime in autumn of this year.
