I have a strong doubt that Tsunami will be in, as she is original OAV continuity material. Ai Tenchi Muyo seems to be another continuity...yet again. Not that it matters. Kajishima ruined the OAV continuity. I refuse to acknowledge OAV 3 and GXP.
I haven't bothered to track down and watch Ryo-Ohki yet but I found GXP to be comical for a decent portion of it. I enjoy all of Nabeshin's work.
Edit: I also need to track down all of War on Geminar for a good weekend.
