In my haste to download the update and get going with patch 13, I came across an interesting site. My version of the launched game is the following: Diablo III Retail. Not Diablo III Beta, or any derivative. Take this as you will, but it seems that the current version of the beta will be the retail version – meaning the game is primed and ready for a release announcement. While this seems to be fairly solid proof, take this with a grain of salt because… you know, it’s Blizzard.
