I'm still not sure what will drop from Zul'Aman (which had the fancy bear mount), but I don't see anything relevant here yet. The last two mounts are obviously the new Zul'Gurub ones, BUT these are not necessarily the final product. The raptor is supposed to be armored according to the notes, so I think they may have just stuck these models in to test with and will update them later.
OMG I LOVE THOSE CUBS!
And... green fire hawk? *grimace* Gogo undead and/or warlock mount?
