Yeah I was talking about that too, "Official English Subtitles" right. Rarely do studios ever release them, if they did so on a regular basis then what would be the use of fansubbing anime?
Most of the time official subs are not preferred, take Crunchyroll for example or funimation, do people not really, really despise them? CR subs and releases an episode of an anime in about 1hr at max.
Fansubs take more time than that except for the speedsub groups but they too revise their previous releases when they release the Blu-ray or dvd-rips. Mf does not have original english subs because if they were then groups like Z-Z (Zhentanim), Exiled-Destiny and CoalGirls etc. would have done them instead of using the subtitles of other fansub groups.
Bandai ent. has licensed Mf and I don't think that they will do official subs as I think they never released official english subs for Gundam 00.
Edit: Cheers for giving me a big hug!
