The official Wrath of the Lich King website has had its Bestiary updated. What's the new addition? Magnataur! They seem to be centaur on steroids, essentially. An amalgam of a giant and a mammoth, these guys do not look (or sound) small whatsoever.
They're also described as fairly vicious, and their description lets us in on another fun blast from WoW past - the return of kobolds! You no take icicle? It sounds like the two races have a fairly symbiotic relationship, which should be an interesting dynamic to follow.
It's mentioned that single males control 'giant herds' which makes me a little curious about how big these guys can really be if they want to represent that in the game. The zones are supposed to be bigger in Wrath, but big enough to accurately represent massive herds of Magnataur? Maybe, maybe not! I guess that we'll see in time.
