Zitat von Shinryu
Two things have been mentioned, both by Peter Garza, the localization producer...
1. Once you have a clear file, you can load up a first playthrough file and be able to access second playthrough content such as the extra dungeon or Mystic Artes. In the original, you had to play through a second time to access such.
2. New Mystic Artes (Hi-Ougi). In the first interview, he stated that "a lot of the player characters" would be getting new ones, and on the Tales forum, he stated that more than Guy and Natalia would be getting new ones. No further details have been mentioned, though.
