Some unconfirmed info comes to us from Vulkoor of Antonia Bayle.
Since I have seen the model first hand, I can verify that the pic[ture of the bear] is in fact the new Dire Bear model, well one of them. Like the Warg, there are armored and un armored version of the mount.
Also as Valk stated, the crafters mounts aren’t new models per se, but old horse models with saddlebags added to them.
