* One of the zone scenes shows a moose/elk (around 1:03). It seems reasonable to expect this would become tameable in the Stag family:
* There's a bird flying in the background of the same moose footage. It's a bit faint but I think it's just a standard eagle model.
* Some footage of a pond in a forest (around 1:12) shows a standard Pandaren-style white crane at the very bottom. But we can always hope they create some new colours. (And if anyone in the Art team is reading, I can provide you with some skin files for these interesting recolours!
)* In some footage (around 1:09 - 1:10) showing a very angry Drogbar you can see a worm covered in bones emerge on the far left. It's difficult to tell but it may just be the old model and may be a placeholder. Its posture makes me think it's yet another in-ground worm, which would be very frustrating unless they make a full version as well.
* In addition we've seen upgraded Druid cat forms. I haven't examined them closely but I suspect they're based on the "Saber2" model that the Runesaber mount was also based on. In which case I would fully expect we'll see wild saber cats of a new model. While we already have 94564568908945064 cats to tame, a shiny new model is always welcome, I say.
* A shot of the "moose tauren" camp shows a kodo skull and some strung-up tallstriders. While these are stock artwork for Tauren villages, we might expect both creatures to be native to the Isles. A new tallstrider model would be awesome. There's already a new kodo model, but so far we've only seen a mount version (used for the new Vicious War Kodo mount).
* One scene (around 0:56) also shows light (with purple or pink highlights? spectral?) hippogryphs flying about, but they seem to be mounts. They seem to be using the new model. They're definitely not the original Silver Covenant Hippogryphs. The point is moot since hippogryphs aren't currently tameable, but it's interesting anyway. Tameable or not, hopefully the new continent will contain wild hippogryphs using the new model.
- Since they're using some of the beasts from Pandaria, maybe we'll finally see the missing purple stag.
the gem and spirit ones are so pretty. Sabers seems like another awesome given. It would be cool if we found updated lynx models too. they were a favorite of mine and they have been long forgotten. also, totally overlooked the proto drake possibility. you are probably 100% right. they would have taken some of their protos with them. *crosses fingers for more proto mounts*
