Here's a new release, and this one was kind of a handful. It's just one volume, but it's a pretty long one. These scans are from the "complete edition", by the way; I've never seen the original, "incomplete" version, so I don't know exactly what's different, but supposedly this one has better closure, though it still doesn't actually conclude the story. I guess you can look at it as kind of a throwback to the original series though, which ended on a similar note.
