Well, they did.
The adultswim.com website just got a complete face lift. And with the new look came a lot of new content.
Amongst that content was the video footage of the FMA guys answering the questions.
You can find the videos here: http://www.adultswim.com/shows/fullmetal/bts/index.html
Also, we got some dub information from the interviews...
- Greg Ayres will be playing the "Lizard Man" chimera
- Tiffany Grant will be playing an undisclosed character (I'm thinking Martel or Grandma-Dante)
