The latest issue of Japanese magazine Jump has a teaser for the "next" Tales game. The article states, "Next Tales of..." and calls this a "next generation Tales".
There's not much info, though. The game's platform is TBA—ditto for its release date and price. All we know is that Namco Bandai Games is making it and that it's a role-playing game. At this point, that's all we need to know.
