New Trailer for STAR TREK: INTO DARKNESS Gives a few Villainous Clues

The new international trailer for Star Trek: Into Darkness reveals a few plot clues, including a bit of the possible origin/motivation of the villain, played by Benedict Cumberbatch. Is he Khan? A disgruntled member of Starfleet? A rogue agent? Frankly, I don't care. All I know is that it's being released in the UK on May 10 (May 17 in North America) and I'm counting the days.
