Gust recently announced Atelier Shallie: Alchemists of the Dusk Sea to be released this July for the PS3, but apparently they have more in store, as they recently filed to trademark "Atelier Questboard" and "Questboard" with the Japan Patent Office.

The trademark is filed under the international classes 9 and 41, which relate to games and online games (or games distributed online).

While it could certainly be a new game, considering the name it's also possible that it could be a companion experience for another game, or some kind of social or online application.

At the moment there's no further information on what it could be, so we'll hve to stand by for an official announcement by Gust in order to know more.
