Arena.Net's Angel Leigh McCoy has revealed that the open beta is in the planning stages now that Guild Wars 2 closed beta testing is underway. McCoy stated as much in an interview with NeverMetPress.com in a larger discussion of her past work and present duties with Arena.Net.

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.
