Its true that Jahiera was not datamined ... yet ... but Chubblot have found her robe wich is equippable by your party members ... and as far as i know (and feel free to corect me this information is 4 ... in few days 5 ... patches old) the only characters we could strip naked, even after killing them to death, was companions (yes that would include Minthara).
she has been datamined already. whatever she said in the trailer had been found 4 months ago. you can have her robe is bc it's something you can get if you play evil path.
