I've been waiting for the Wind Rider Cub ever since I saw the pictures on MMO Champion! And they come with Plushies! /Squeal!The Pet Store is about to go plush! Introducing the Wind Rider Cub and Gryphon Hatchling, the first in a new line of cuddly, crafty critters scheduled to arrive exclusively in the online Blizzard Store in the weeks ahead. Each plush companion will come with a code for a matching in-game, non-combat, account-bound pet to fly by your side in Azeroth. Both Horde and Alliance players will be able to adopt either pet once they hatch in the online Blizzard Store. Keep your eyes on the sky -- and the official World of Warcraft website -- for more information.
Found some nice pictures!

The Cub in this picture has no wings, but it's just the basic body model, and wings will be on the actual pet.
