WOW.
Apparently they're already on the third episode, the last time I heard about this series it was still in pre-produciton. Take a look at the three preview videos, it looks like they're using even more CG than The Galaxy Railways.
I'm still not hooked on the Great Yamato design. But, anything new by Leiji Matsumoto and company can't be bad at all.
Check it out.
