Thanks for the information and it's definitely interesting that people are posting about our Game Testing Program. We don't have anything official to say at this moment but if you have any questions, please check out the Game Testing Program FAQ.
We can confirm the image in the thread is similar to the launcher graphic we saw at E3, which gives some strength to the rumor in addition to the "yellow text post and no lock" response.
Update: Sean added more (Hat tip to Tyvarion) on the subject, reminding people what potential testers are allowed to say:
The Game Testing Agreement that was agreed upon (when signing up for game testing) states:
1. The fact that there is a Game Program.
2. The fact that you are a member of the Game Program.
Outside of that, it is a violation of the agreement to do anything more such as posting images or screen captures of anything related to Game Testing that is private and confidential and not already publicly revealed by The Old Republic team.
