The translation/editing were already done when the leak came out, the leak was just an old script hardly edited, that came out long time ago before it was completed. All that was left was the installer, which took nearly half a year to complete.
So of course fan would be eager, would you want to wait 6 months~ just for an installer that could make toast for you,
(There was a topic about "The installer is so great..." in which peoples made up stuff about the installer, on the mm forum)
when you already know that the damn thing was already translated/edited a long time ago and they could have just released the files into a .zip or something so that we could manual patch the game ourself? Even if they do this in their free time, that was just too much.

Anyway, there's no point talking about this, that was in the past and we can just hope history won't repeat itself.
