I'd expect the open beta by the 7th-15th of next month. I'd tell you what phase they are on if I wouldn't get censored for a document that I never had the privilege of agreeing to.
Even though I have wanted to desperately play this game for 3 years, I have started to become a bit more wary in the last couple months. SE as been overly selective of those that get to participate in the closed beta, which is fine. The problem is the majority of their beta has been testing one part of a supposedly huge game. Yes, phase three is supposed to bring in the other cities, but that doesn't leave much time to have people test all of the content the game will offer, especially the end-game content. If there are some major issues that might need to be addressed I don't think that they will have the ability to test those issues again before the beta ends. With a large portion of their playerbase going to be ready to tackle this content (and it being one of the biggest contributors to the downfall of multiple recent MMOs) you would think that they would spend more time with this content open to testing.
