1. The Wind Rider Cub is now back in stock in the Blizzard Pet Store! US only at this time.I've heard that EU players can purchase the cub plush + pet and the code will work for EU accounts. However, I must stress caution when doing this, as I'm not sure if this is supported by Blizzard. If the code doesn't work, it's possible that they will assist in getting a working EU code for you, but it's also possible that they won't. So purchase at your own risk/discretion.
2. Blizzard has finally announced the goodies for this year's Blizzcon event, and yes, one of those goodies is a pet. Murkalot!
As for the Blizzcon goodie, it looks like they're releasing a WoW pet with the theme of the new Diable class, the Crusader. But honestly, when I look at Murkalot, I can only imagine him yelling "ONE, TWO, FIVE!" and then throwing a Holy Hand Grenade. :P
On a serious note, though. If you plan on purchasing a Virtual Blizzcon Ticket, keep in mind that you cannot sell the pet. After purchase, you receive this message:
"BlizzCon 2013 In-Game GoodiesOnly those who will be physically attending Blizzcon and/or receive the physical scratch card with Murkalot code will be able to trade and sell it. If you want to give someone the pet via Virtual Ticket, you'll have to purchase the ticket through their account so that it's bound to it.
Your BlizzCon 2013 in-game goodies for World of Warcraft, StarCraft II, Diablo III, and Hearthstone: Heroes of Warcraft will automatically be added to your Battle.net account. After the goodies have been officially released to players some time after the start of BlizzCon 2013, you’ll be able to access them in-game when you log in using this Battle.net account. Keep an eye on www.blizzcon.com for more information."
