World of Warcraft's upcoming major content patch, Call of the Crusade, is expected to deliver a new 80 player battleground. Much like Alterac Valley, the new battleground "Isle of Conquest" supports up to 40 players on each side. Both the Alliance and Horde have keeps which house the factions' generals - who can be killed to claim victory. Also akin to Alterac Valley is the reinforcement system and the ability to capture various points on the map.
This isn't to downplay the latest battleground as a rehash. The Isle of Conquest also includes siege weaponry and vehicles to be taken advantage of. By controlling certain points on the map, your faction can use the associated weaponry. Some of the featured siege weapons include the Glaive Thrower, the Catapult and even an airship. These weapons give the new battleground more dimension and room for strategy than Alterac Valley.
Also included in this patch is an expansion to the Argent Tournament, the Crusaders' Coliseum, and the beginning of Arena Season 7. As always, if you wish to preview this patch you can give it a whirl on the Public Test Realm. Blizzard has yet to announce an official release date for patch 3.2. That said, based on pure speculation, I foresee its arrival in late August. If Arena Season 6 is to follow the two previous seasons, its duration will be 17 weeks, ending August 18 with Season 7 commencing the following Tuesday, August 25.
