Lovely campaign, even if unfinished. I have two questions about the 2nd mission, though. It's literally been years since its release, so I guess unspoilered is okay, and makes for better searchability in the future.
I believe you are referring to Goldchocobo's plans to expand this to 5 missions. Probably still in the cards if Gold's, Mortem, and Biker get things rolling again someday.
