The Tales of panel at Anime Expo 2014 brings forth Tales of Hearts R's North American release date, as well as a little Tales of Zestiria tidbit.
At the panel were Minae Noji and Lauren Landa, the voice actors of Milla and Leia respectively in Tales of Xillia and Xillia 2. They confirm that Tales of Hearts R's North American release date will be on November 11, 2014.
In addition, a short, subtitled trailer for Tales of Zestiria was shown to the audience. In a scene where Mikulio talks to Slay, the subtitles termed his name as "Sorey."
Thanks to Varrius who was at Anime Expo for the info.
