There is a new manga, 'Gunnm - Last Order' which is now being translated into english by Viz comics. It is offically the proper ending of the Battle Angel Alita series. It picks up where the 'Angel's Ascension' left off, finding Alita reborn in the new Imaginos body, and in Tiphares for the first time. I have read most of it, translated online, but I've yet to discover the ending of this awesome manga. Should be something to look forward to! Brand new characters, new enemies, and definitely something to discover if you are into manga.
