In a new interview with Gouda Tsutomu and Higuchi Yoshito, who are working on Tales of Vesperia for the Xbox 360, they are asking whether the game will arrive on the PlayStation 3 or not. Higuchi Yoshito answered (warning: rough translation).
Q: PlayStation 3 is scheduled for release?It seems he is trying to say the game will be coming out for the PlayStation 3, just a bit after it is released on the Xbox 360.
A: Higuchi's SHINFONIA, when the GameCube too specialized and because of the PlayStation 2 when transplanted to the lower frame rate, a considerable ingenuity. PlayStation 3 is a very sophisticated, so in that sense I think the same thing can be reproduced. However, it will be released, and what is not yet.
