World of Warcraft v1.9 Patch Overview

GameSpy has put together a detailed overview of Blizzard's newly released v1.9 patch for World of Warcraft. An excerpt about the expanded auction system:
At long last, WoW's Auction House systems are no longer centered in a single city. On the Alliance side, new AHs have sprung up in Stormwind (near the bank, in the Trade District) and in Darnassus, while the Horde have new houses in the Undercity and Thunder Bluff linked to the main one in Orgrimmar. Additionally, the cross-faction Auction House in Gadgetzan now has two more extensions in Booty Bay and Everlook.

There was some question among players whether this would de-centralize Ironforge and Orgrimmar as central hubs for players to meet and create groups, but the new patch links the "Trade" and "Looking for Group" chat channels in the major cities, so players in Ironforge and Stormwind can now chat on the same channel while looking for groups.
