At their Anime Expo panel, Aniplex USA showed a trailer of footage from Mikunopolis, indicating their intention to release the product stateside. Previously, it was only available as an import with BD, DVD and CD versions, making it difficult to acquire for fans outside Japan. The official website will eventually contain information for the upcoming release.
UPDATE: An employee at the Aniplex USA booth in the Exhibit Hall clarified that this will indeed be a BluRay release and is scheduled to come out sometime this year.
