Although, full season box sets being risky? I don't get that logic.... I mean, I get it in a big businessy sense, but in a normal human logic sense? No. It doesn't cost that much to produce DVD's.  A simple, bare bones, full season release would NOT actually cost them that much to develop, and there's no way they'd LOSE money from it.... Unfortunately, most all companies aren't worried about losing money, they're worried about not making enough.
