No plans for an international release have been announced, but Level-5 filed a trademark for The Little Battlers eXperience in the USA. This trademark isn’t just for video games. It also covers plastic models (the game came with one), animated television shows, comic books, and all kinds of related merchandise.
Perhaps, Level-5 International, the company’s North American branch, is thinking about localizing the series. Right now, they’re running a poll to gauge interest in various Japan-only Level-5 titles. You can vote for your favorite with your Facebook account here. As of this writing, Professor Layton vs. Ace Attorney is in the lead with Ninokuni for PlayStation 3 trailing in second place.
A tip of the hat to Liam for the heads up. Thanks!
