i think its wrong to say that the release is 2012 now..sure..his comments + this company list shows some clue about this BUT this is blizzard...they suprising us with different dates all the time and than they release the game on a completley different date (for example...christmas time).
I still think they will release the game at the end of the year or early januar 2012 because the beta starts this year (100%). Saw an article about that in a german game magazin who talked to blizz .
So beta this year and than release or they wait for early januar.
