I feel like we won't get any real information about them til 3.4. Maybe a teaser again, but not much else.
They definitely have a reason for staying with the Resistance, and I bet it has something to do with that masked man from 3.2. Whoever he is, he's probably really important and could be either a great ally come 4.0, or a main antagonist.
Darksteel-foil hat time, I personally think it may be...Gaius. And if it is...well, all the more reason for Yda and Papalymo to be hounding him...
But...that doesn't make him automatically an enemy...look at Nero, after all...
Also, if they are near Ala Mihgo, information from the city-states is probably scarce. Especially from Ishgard. Its possible they may have heard something about the WoL, but it may just be rumors and such reaching them, and chasing rumors may only hurt their efforts with the Resistance.
