They have the torrents for 10 and 11 but I haven't seen listings for 1-9 for a while. I think they dropped them because they were inactive for too long.

I looked up those other groups... they're disbanded so they won't be finishing either (in fact they stopped before Seichi even started). I guess that we just wait for Seichi, or for someone else to decide to pick it up (or for it to be licensed).
