Tales of Symphonia Chronicles will have costumes from Tales of Xillia.
Kratos will be able to wear a Ludger outfit (from Tales of Xillia 2), while Zelos will have an Alvin costume and Presea an Elize costume (from the first Tales of Xillia).
You can obtain the costumes on your second playthrough of the game, but if you have save data for Tales of Xillia or Tales of Xillia 2, you can get at the start of your first playthrough.
Two new heads for the Tales of Symphona: Dawn of the New World‘s head accessories feature are also revealed. Emil will have access to a Mecha Emil head, and Malta an HMD head (I’m guessing a that means a helmet-mounted display).
Gallery mode will have over 100 artworks.
Thanks, Tale Tale Source.
