So, we heard from the devs that unreleased genders would be looked into and hopefully released alongside the PS3 release:

Hey everyone, sorry for the delay in getting this response back to you!

We talked to Yoshida and one of the things he mentioned was that the number of people wanting a female Roegadyn was pretty unexpected! He wanted us to let you know that the team will do their best to introduce missing genders alongside the launch of the PS3 version.
However, with a recent translation of the German lodestone page, it is confirmed that Merlwyb is a Roegadyn (at least in at least 2 European translations, French as well I hear.) It mentions that she is 'one of the few' female roegadyns, which is a troubling remark.

Simple Translation:

"Merlwyb ist nicht allein aufgrund der tatsache aussergewöhnlich, dass es sich bei ihr um eine der wenigen weiblichen roegadyn handelt, nein, sie bekleidet als Admiral auchnoch gleichzeitig die Ämter der Staatsoberhaupts Limsa Lominsas und der Oberbefehlshabers der Thalassokratischen Kriegsmarine."

"The fact that merlwyb is one of the few female roegadyn isnt the only reason shes exceptional, no, at the same time she, as the Admiral acts as the Head of the state Limsa Lominsa and as the highest general of the Thallasocratic Marine"

Borrowed from the original poster and Cairdeas
Yoshi-P's statement on the matter is vague at best, as he never states that they are considering releasing them as a playable option, at least not in so many words.

I was curious if the Devs could get a more solid answer for its English player base. This is not a thread requesting they be released immediately, or to be insensitive to others who wish for more practical patches first. Even if it's a minority of us, we do want to know for sure so not to get our hopes up. D:
