Yeah, Shout isn't like Disney. While they may be slow to release the next volume (ie Conan the Adventurer), usually when they start releasing a series, they release all of it.

Further details have been announced:

*Volume 2 will be available starting "Fall 2012"

*The COMPLETE Season 1 boxset will only be available online

Yeah, and that is how they were doing their Transformers and GI Joe sets.

Anyone know if the audio will be Dobly Digital or just Stereo?

I'm going to guess stereo since Shout does not do any remastering of the audio. They just use whatever is given to them.
