Confirmed by Hideo Baba earlier today at Japan Expo, Tales of Symphonia Chronicles will indeed have dual audio as rumored by Gameinformer last month. Tales of Symphonia Chronicles is the HD remastered version of the PlayStation 2 version of Tales of Symphonia and the Wii version of Tales of Symphonia: Dawn of the new world. The english release will feature both Japanese and English audio tracks. It's unclear as to whether the Japanese release will have dual-audio as well. The game is set to release later this year in Japan and early 2014 in the US and Europe.
Hideo Baba, also teased an additional announcement on July 6 during another Tales panel. Most likely this is Tales of Xillia 2. Considering the timing of Tales of Xillia's announcement last year and how it coincides on the same timeframe for this year, this is the most probable answer.
