Paramount Home Entertainment has revealed that they will release its first BD-Live feature - a video called "Robot Ninjas' - for the 'Transformers' Blu-ray on September 30th. The video will focus entirely on the battle between Bumblebee and Barricade, showcasing home videos and animatics gathered from the film's stunt crew.
The second BD-Live feature, called "What Effing Happened in Mission City", is coming soon. It is also expected that Paramount will use the BD-Live features on 'Transformers' to promote the sequel, which is filming now.
Now it's just a matter of how to keep up with BD-Live extras, since you'll otherwise not know about them unless posted (like here) or you put in the BD and check for extras.
Where do you sign up for info on the extras, Geonosis? Just regular ole Paramount site?
