Brewfest has apparently been activated on the Public Test Realm. This event normally occurs in October, but Blizzard has been activating some of their events early on the PTR to make sure they run smoothly. If you are done with the Midsummer Fire Festival on live, you might want to take an early look at Brewfest on the PTR.
Unfortunately, there is some bad news involving the Brewfest reward mounts. From now on, only Alliance characters will have access to a Brewfest Ram, while only Horde characters can get the new Brewfest Kodo. But I’ve already ranted about it on Warcraft Mounts so I’ll just point you over there for that.
Oh, also I hear that Arena Season 4 has started, whatever that means. *grin*
 I forgot to mention that pre-made characters are now available on the PTR as well. Unfortunately, the queue for copies is currently full.
