Shonen Jump has a picture of Pascal decked out from head to toe in a mascot-style Toro costume. Namco Bandai plans to release the outfit as downloadable content. The Hatsune Miku costume for Sophie is also confirmed for the PlayStation 3 game.
Will this be as big as the Keroro costume with its 35,000+ sales? Probably not, but every Tales PS3 port apparently needs some kind of out of place costume.
