Gaming Steve brings us
information that cross-realm battlegrounds, of a form, will be coming to Azeroth. By patch 1.12 or 1.13 "at the
latest", battlegrounds will span sixteen realms, allowing for shorter queues and new opponents.
There are also some more exciting BG changes planned for the future, turning WoW PvP into a truly competitive sport with tournaments, ladders and worldwide rankings to take part in. It looks like we'll have to wait for the Burning Crusade to see most of the changes, but bringing cross-realm combat in sooner rather than later is something I'm definitely looking forward to.
