A Star Wars: The Old Republic beta tester broke their NDA this weekend by streaming more than two hours of gameplay to Justin.tv. There’s now an archive of it online in which you can see character creation and a bit of Sith and Jedi gameplay. The entire thing runs two hours and you get a good sample of the combat and voiced dialog. Who knows how long the archive will remain up, but until BioWare manages to take it down you can view the footage right here.
Edit: First mirror has been taken down. Thanks Digg user hybrid11 for providing this link (get it while you can, it will probably get yanked as well.)
