Here are Screenshots of the New Mounts that are introduced with the new PTR Patch 2.3. The Engineer Flying Mount, Hippogryph Cenarion Mount and the most awesome looking Bear Mount from Zul'Aman:
The Bear Mount is the coolest Mount ingame, it really looks awesome. Also the enigneering Mount, which will not backfire as the other engineering gadgets, looks really nice.
No way though I will spend 2000g for the Hippogryph Mount, the most ugly thing I have ever seen.Yikes.
