People in trade chat, on Cenarius US are reporting 85,000 in queue for the pet.

If the mount was a 310% on its own, even if you did not already own one...
Especially if you could choose the mount graphic, I'd probably pick up the Tempest Keep phoenix x5.

But for a pure graphic mount, not worth it.
You'd still have to pay for epic flying etc.., so its not much of a gold savings.
