I just got an email from Sean Dahlberg, Star Wars: The Old Republic Community Manager, with the following text:
While we have not announced a specific date, we can confirm that we are targeting a spring 2011 release for Star Wars™: The Old Republic™. We’ve got a lot of exciting updates and reveals planned throughout 2010, including the first-ever hands-on testing for the game. It’s not too late to sign up to be a game tester, so go to www.swtor.com/tester and sign up today. We can’t wait to share more about the game with you as we progress through the year, so make sure you stay tuned to the official website for details.
You can also read the update on the official forums. Thanks Sean.
Note that this is a target; they might miss their target it if they run into problems or such. This isn’t an official release date announcement.
