Blizzard Entertainment has put an official announcement on their corporate website. It includes a brief game overview and FAQ of both the Beta test and the new Auction House. All the information beyond basic signup and usage is pretty vague. Give it a read, but don't expect much in the way of exciting discoveries, especially if you have kept up on Diablo III news from other sources.
