What can we expect from Patch 1.12? Check out the Under Development page which outlines:
Coming in patch 1.12 are cross-realm PvP Battlegrounds
objective-based land battles as Horde and Alliance vie for control over important strategic positions and resources around Azeroth
One thing I like about Blizzard - If you mouse over the picture at the top of the Under Development Page each character in the pic has a funny quip. (Thanks to this post that mentioned that little Easter Egg.) The Orc's mouseover-text has been updated because people must have felt the Tauren was confusing. (Unfortunately the mouseover-text didn't copy over to this post.... go on over to the Under Development page to check it out.)
