Japanese developer Q Entertainment has mostly stayed out of the limelight since releasing Lumines Supernova for the PSN last year, though a recent trademark filing may hint at the developer's plans for the future. The relatively young company just filed its sixth trademark ever, reserving the title Guardian Hearts for future use in a video game.

We usually remind our readers that not every trademark a developer files ends up turning into a game, but in Q Entertainment's case, they actually do. We've contacted Q to find out whether this might be the moniker of a forthcoming project, and whether the actual game will be as RPG-ish as the aforementioned appellation.
