Japanese gamers will be able to test the PS3 version of Tales when a free downloadable demo releases next week, July 13th. If you make a Japanese PSN account of your own, you'll be able to try it -- just make sure you know Japanese first, okay?
We contacted Namco Bandai Games America about its plans for a US release and were simply told, "We have not announced Tales of Vesperia (PS3) for the North American region at this time. Therefore, we can not comment on additional content for the PS3 version of the game in Japan." Shucks.
