I hope G-Reco isn't going to turn out like Arjuna, with screechy, preachy environmental messages spewed around everywhere. That doesn't do service to anyone.
I can see where Tomino comes from with his comments about voice actors though. I like it when a series uses natural voice acting, such as in Flowers of Evil or Mushishi, instead of the hyper-stylized voice acting you get in most anime.
I think a lot of that is due to seiyuu culture unfortunately.
