Damn near everyone in the background of that video was in costume, so yeah... Hey, whatever. I guarantee there will be CGI characters too though. I feel it's inevitable.
I don't mind CGI stuff... Sebulba was pretty extraordinary, especially at the time. Honestly, even Jar Jar was pretty state of the art at the time.
I liked the weird thing that wandered through the shot, but yeah why read anything into any of it?
I'm just glad Abrams seems to be attempting to reinforce that he cares about this, and doesn't want to piss people off. I'm sure he will because if there is something more picky than a Star Trek fan it's a Star Wars fan, but hey I'm just along for the ride no matter how it turns out.
Then again I liked both his Trek films. I'd love more of those honestly.
