I feel conflicted about that trailer. It doesn't look bad (except for the lightsaber shape and blade flickering that is too reminiscent of TFU to me), but doesn't completely feel like Star Wars either. Guess the best thing to do is wait and see.
People always seem to reject new ideas...but that's what made star wars great remember? It was new...something people hadn't seen before...I hope the new trilogy takes it in this path.
