Diablo 3 - Wizard Video, Auction House Overview

The Diablo III site has been updated with a new Wizard video and an overview of the Auction House system:

Which auction houses you have access to is determined by where you live -- specifically, the country of residence registered to your Battle.net® account. In general, players can access the gold auction house in every game region, but can only access real-money auction houses in their home game region.

Each of Diablo III’s three game regions -- The Americas, Europe, and Asia -- has its own separate set of gold- and real-money auction houses (one for each supported currency in the region). See the table below for details. Each auction house is completely independent, meaning items listed on one do not appear on another.
