BioWare VP Greg Zeschuk posted the announcement just minutes ago on the forums:
As of now, the non-disclosure portion of our Game Testing Agreement is officially lifted. While all players must still accept the Game Testing Agreement, from this point on testers may now freely talk about their experiences this past weekend in the game, as well as post screenshots and gameplay videos of their testing experiences. We encourage you to come join us on the official Star Wars™: The Old Republic™ Forums to share your experiences!If all that wasn't exciting enough, the dev team also released articles covering the flashpoint Bringing Down the Hammer, the book, The Art and Making of The Old Republic, and the Legacy system, which allows for a family last name shared across characters.
The Star Wars: The Old Republic community site will have a copy of this message on the forums and it will also appear in the Patcher. Players may not talk about nor reprint posts from our testing forums as they are still fully covered by the confidentiality portions of our Game Testing Agreement. And all players who want to participate in the upcoming Beta Test Weekends still have to accept all terms of the Game Testing Agreement. So, other than that, free feel to talk about and share your experiences in Star Wars: The Old Republic.
