The next story chapter is centered on Yda and Papalymo, so I assume that'll sort out when the rest of the XIV cast was taken from.

I do hope they release more XIV characters soonish, though. Praying they'll throw us a curveball and make Emet Selch (Complete with requisite swagger and finger snaps) a playable character before Zenos to capitalize on ShB's popularity. They have both Kam'lanaut and E'aldnarche from XI now, so doubling up on villains from the same game isn't an issue to them, evidently.
