Blizzard recently released images and info regarding the Pandaren mounts – A Dragon Turtle!
Pandaren Dragon Turtle Lore:
Pandaren have always sought mounts that embody their own values and ideals — strength and patience. The Dragon Turtle is not only a strong and well defended creature (it’s pretty big and has a hard shell), but they are also easily outfitted with any equipment a traveling Pandaren may need. They’re comfortable to ride, sturdy for long journeys, and even ready for battle if duty calls.
