It was mentioned but only in relation to Battlenet 2.0, nothing about the game itself... no new revelations on content or beta much less release. Unrelated to the call, they have released some updates to the monk character:

Just my guess... Diablo III beta at least a year off. They still have lots of stuff to tease with and they love to tease. They also usually announce the beta is coming several months before it actually arrives... plus they tease the beta announcement is coming several months before it does so... absolute minimum for beta would be September and since they still have one more major reveal (the last class) with no hints yet, I don't see it that early. A lot of people think they announce games to early, makes people think the game is taking to long but I don't think so. I think they really have it down to building up the frenzy.
