Just a quick update this time.
Cataclysm Alpha Started, that's a special testing period, where only blizzard employees and their friends and Family can log in to the special Cataclysm servers and check things out (and hopefully help test the expansion and improve it etc etc).
That means that the Cataclysm Beta will soon follow, and with it a lot of new content will be revealed, so... stay tuned.
