I can't believe it's really happening. I still think of this game as being so far off, but it's really not.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.
For those that didn't know GW1 had Open Beta weekends, where anyone could log in and play over the weekends. It was what really hooked me on the game. Hopefully this is what GW2 is planning to do, I can't imagine them straying from it since the system worked out really well with GW1.
There's no date or anything, just mention of them planning open beta. But the fact that they are even planning for it means it can't be tremendously far off.
