BioWare didn't show any gameplay during the EA conference just now, but there is an opening cinematic of Star Wars: The Old Republic for you to enjoy instead. There's Sith vs. Jedi, early model Droidekas, and Sith destroyers that already resemble Imperial Star Destroyers. Because it autoplays, check it out below.
The CG looks good enough, but a release date and actual gameplay is what people want right now. Hopefully BioWare can use the extra time to make SWTOR what it is supposed to be: a great Star Wars MMO.
