So... basically a a remake of the series with redone animation and some new bits (including a new ending). I'm interested. I love the original show, but became so disinterested with the sequel series, AO, that I still haven't finished it (I think I haven't seen the last two episodes?). I'm glad that the writer, Dai Sato, is back. AO convinced me he was a bit part of what defined the series, because that series had the same director and designer but was missing him.
