Namco Bandai has filed a trademark in Europe for something called Lost Swords. The trademark encompass various video game jargon, and as Siliconera points out, it doesn’t seem to be connected to any particular title in Japan. While it could be something new it could also be a subtitle or a name change for a title currently available. We’ll send a mail and ask. You can look over the entire trademark filing here. Thanks, AGB.
