First, for all of you who wanted a spectral tiger, you get a see-through horsey called "Celestial Steed." (No photos, but the "Celestial" pet is see-through and sparkly. Yes, I'm too sleepy to actually post the image.) I don't know how or where you'll get this horsey mount, but it'll probably be somewhere fancy and difficult, like killing Arthas's mom in 25-man hardmode where if you stand in her Guilt Ray, you die instantly of shame.
Next news, there's a rocket mount that seats two people, so we do have multi-player flying mounts coming soon.
Down side, it's not pink. I know this breaks a lot of hearts, but we have to keep our chins up until they realize how much pink rules.
