The latest beta build of Warlords brought with it several new Battle Pets as well as the mount pictured above. Yes, that is a Core Hound, and yes, you will be able to ride it by obtaining euwowgold the Core Hound Chain. Although it's not directly stated where this mount will be obtained on the mount tab, it's safe to say we'll likely see it dropping in the newly-revamped Upper Blackrock Spire. After all, what's Blackrock Spire without The Beast?

In addition to the Core Hound mount, several Ravager Wasp battle pets were added, along with a Runtish Gronnling, and a pet named Sky-bo that appears to be a miniature version of the Sky Golem mount. At the moment, there's no indication whether Sky-bo is an engineer crafted pet. To check out 3D models of the new Core Hound mount, as well as other new items added to the beta, head over to Wowhead.
