Lo and behold the first English language trailer for Project X Zone, due out in North America on June 25 and Europe on July 5. You'll note a lack of voices, but it's already been confirmed the final game will retain the original Japanese voice track.
In other Project X Zone news, Namco Bandai confirmed the game will include a mini-art book, poster, and music CD. The whole package will run you no less than $39.99.
