According to the official Macross Frontier Blog, the 9th DVD of Macross Frontier will be released on April 24th in Japan. The DVD will have a special message from Shoji Kawamori (series creator). A long with that, some of the cast members have provided audio commentary for the last episode of the series. The last episode is #25 and its titled "Anata no Oto" or "The sound of you" in English.
Here's a picture of the cast with Shoji Kawamori during the recording of the audio commentary for episode 25.
Cool!, Too bad its not in english. Off tangent a bit, but I wish they'd hurry up with the Macross Frontier movie though, that would be much better news to hear... hehehe
