STAR TREK: INTO DARKNESS Teaser Trailer

The question is whether Benedict Cumberbatch is actually playing Khan Noonien Singh. I kinda hope he is.

(If, by the way, you haven't heard of Cumberbatch, you will hear a lot over the next couple of years. He's already had a very full career, and in the Hobbit movies he's playing both the Necromancer [who eventually becomes Sauron] and voicing Smaug the dragon. And he's the star [along with Martin "Bilbo Dent" Freeman] of the BBC's superlative Sherlock reboot.)

There is also a Japanese teaser trailer that has an extra ending tacked onto it.

Thoughts?
