Blizzard released the much anticipated Battlegrounds today. Check out all the details from Blizzard below.

New World of Warcraft Patch: Battlegrounds!
We're pleased to announce that the latest patch has arrived, and included are the first two Battlegrounds. Nestled high within the Alterac Mountains of Lordaeron is Alterac Valley, where teams of 40 complete PvP quests, enlist the aid of powerful NPCs, and clash over strategic objectives in an all-out battle for domination. And in the Northern Barrens, on the highly contested border between Horde and Alliance territory, lies Warsong Gulch, a fast-paced capture-the-flag-based Battleground where teamwork and strategy are the keys to success. Simply log in to World of Warcraft to begin downloading the latest patch and start in on all the fun.
For additional information on World of Warcraft's Battlegrounds, please visit the new Battlegrounds mini section, which contains information about the rewards for both Alterac Valley and Warsong Gulch, as well as each Battleground's score screen!
