When asked about the release date (a sensitive subject) they got the following answer:
That last question is the big one, eh? And, I cannot answer it because I don't know the answer. What I can tell you is that we're currently in Closed Beta and planning has begun for an Open Beta. It's all extremely exciting, and the game is coming along smashingly. It really is like magic when it all starts coming together and you see what an enormous accomplishment you've contributed to.
One can only guess that NCsoft wants to create some space between Star Wars: The Old Republic, Diablo III and its precious Guild Wars 2. From what we've seen and tried of Guild Wars 2 is going to be well worth the wait.
