Blizzard has confirmed the Cenarion Expedition will offer a Hyppogryph Flying Mount through a vendor in patch 2.3 for any adventurer deciding to buy one. However, it has a high cost.
This is the second flying mount this new patch will add to the game. The first one was the Engineer crafted Flying Machine hailing from Warcraft II: Tides of Darkness. These will be available from a Engineering Trainer.
Bornakk: It’s a Hyppogryph. When patch 2.3 is available on the Public Test Realms, hopefully the Cenarion Expedition will let you take a look before purchasing. The 2000g cost is not a typo and intentional. Every time you see one you’ll know the dedication and enjoyment the player has for their new mount.
