I've been told by Hikari Senshi's Go Go V translator that the show's scripts are done, and it's just a matter of getting it through the editing process. I believe other groups have been told about this as well. In light of that, I can't see anyone else devoting resources to that particular show, not unless... I dunno, two years pass and Go Go V still isn't out? There's so much else that isn't touched yet, most people would rather focus on that.
Gingaman... you know, I'll be straight-up honest. I really like Gingaman. I have the resources at my disposal to do Gingaman, if not the time. But after my work on the Megaranger project is finished, I probably will have the time. And despite my feelings about needlessly duplicating translation work in a tiny fansub community, the thought of finishing Gingaman is really, really tempting. We'll just have to wait and see how things go. Gingaman only lacks 10 episodes, and very easily could be finished by the time Megaranger is out in the wild.
