That's a bad summary of the whole press event script at the end of the post.
Here the full quote:
Nowhere in this quote it is stated that the cloud serpent is the racial mount... It's a simple interpretation of "have trained and raised as mounts". But in the same sentence it's also stated that you'll have to train those mounts for yourself with a lvl 85+ daily quest chain, which somehow makes the "is the racial mount" interpretation rather unlikely.We really want to give players a lot of things they can do with their character, especially at max level, regardless of what type of player you are. The Pandaren have trained and raised these cloud serpents as mounts. Would you like one of your own? Of course you would! You can work with these guys over the course of 20 days or so to raise your own cloud serpent
You btw completely ignored the part about the Tom Chilton interview stating that the Racial Mount will be the Dragon Turtle...
