Yeah, that's a pretty early build. They didn't show much to get excited about. I try not to watch making-of stuff because I like to be dazzled by the final product and discover elements as they were intended -- but this one had virtually no spoiler-y material.
I especially like how the sound designer was put on the spot to explain what made the sound different than the first game. "I don't know," he seemed to reply, "we have... themes... which focus on... um... themes... um... focus..." And then his head exploded.
