I'd be pretty unhappy to see anything other than chocobo mounts in this game. Give them a variety of colours and possibly implement a way to gear them (like the armored chocobos of Ishgard) is more than enough variety for mounts. I like chocobo breeding and I don't want this game to continue off into the "generic MMO" direction as opposed to the "Final Fantasy" direction it should be heading towards from the start.
