Alternate Gestures/Poses

I've been noticing that a few NPCs have certain poses that aren't available for us to use (yet) like that one Elvaan NPC behind the bar at the Brume or these guys:

I just started playing back in November of last year but I know SE tends to add new cPoses every once and a while. Has there been any word on new gestures on the way in the upcoming expansion or future patches that anyone's gotten word of?

I'd love to have that stance for my PLD :-D
