Back on topic, the trailer looks great. But then again so did the trailers for I and II. Fool me once, shame on you. Fool me twice, shame on me. Fool me thrice, you must be in marketing or politics.
I like the digital heartbeat at the end. I hope that doesn't become something GL goes back and adds to the OT though to make Vader consistent throughout the trilogy. I won't put it past him.
