Holy crap!!!! That is awesome, I'm interested in a fourth season *waves hand*. That's so cool they got the original voice actors too. It gives me hope for them giving Nadesico a second season or at least a another movie that answers something's.
Anyway, that's just great. I wonder if the character designs will ruin it though, so many years since the last Slayers, will they try to "improve" on things that don't need it. Remember the original Saber Marionette J, and the ugly new character designs for J-X? (I thought they were ugly anyway.) If they do change the character design, I hope its because the characters are older.
