At BlizzCon 3 beta keys were distributed to 1000 Diablo casual visitors.
So slowly a light at the end of the tunnel seems to appear because Blizzard therefore a closed beta is already planning shortly to Diablo III. If this were only the case in 2011, we probably would have used the BlizzCon 2011 on the allocation of these keys.
The blog "VG247" Jay Wilson just wanted to confirm that Diablo 3 is more than halfway finished This can be seen as Blizzard expert but some get read, because it is usually "When it's done" is, once you ask about the progress of a project. May thus announces a release for the 10th anniversary of Diablo 2 Lord of Destruction, which saw the light of day in the summer of 2001.
Would be interesting is the date of the next BlizzCon or Worldwide International (WWI), since Blizzard uses its own extremely fond fair events for large publications.
