The new TV series "Thunderbirds are GO" was released on DVD in Australia. The 13 part series is spread out over 2 DVDs. The first has 7 episodes and the second has 6 episodes.
The only drawback is that it is region 4 encoded and has a PAL signal. However, I know some of us might have DVDs which can still show the videos. No word yet on releases in other countries or on a BluRay release.
The discs are 1.78:1 picture ratio and feature Dolby 2.0 sound.
The DVDs are currently available for $15.95 AUS each. Here are the links:
