Not sure why people are too surprised at it being a recolour when the majority of the previous tw vendor mounts are recolours too. The only one bordering on the unique (or hell, probably is) is the Ironbound Wraithcharger from WotLK. If they added 2 like with WoD tw, then maybe we could've got a ground and a flying mount (hint hint infernal).
I was. Hoping for the high mountain eagle or something unique.
in all honesty, i was kinda expecting an Ur'zhul recolor, but nope, another dime-a-dozen hippogryph. oh well, one more mount for my collection, we REALLY need achievements for 450 and 500 mounts, now
