I don't think Dragoon will receive a wyvern, it'll be like kain highwind from FFIV, since I think they'll go for iconic builds for jobs like Cecil's gear for DRK/PLD or Kain for Dragoon. My thing is if classes were to receive more than one advanced job, what would lancer receive outside of Dragoon, unless they made a polearm war type or polearm sam type. THis is of course assuming advanced jobs are weapon locked.
