When asked about the Beta, Blizzard didn't give a direct response but they did say "We're not years away... we're not even quarters away at this point" which gives hope to the Summer Beta fans have been longing for.
Blizzard does admit in the interview that creating an entirely new engine for the game as well as some other "bumps along the way" have helped to contribute to the extra waiting time, but like everything Blizzard does, that just further justifies how much better this game is going to be!
