Tales of Vesperia on PS3 is set to have some Premium DLC - meaning it has to be paid for.
Namco Bandai hasn't gone into detail regarding what players will get for their money through the Playstation Network, but it is likely similar content to that which was made available as a download for Xbox 360.
One thing they did confirm is that the DLC would arrive beginning September 17th. Interestingly, the DLC will feature the "Trial Synthesis Kit", which was free over on the Xbox 360. We'll bring you more as we get it!
