the Star Trek villian is… John Harrison?

Up until today, most people have assumed that (the great) Benedict Cumberbatch was playing either Kahn or Gary Mitchell in 'Star Trek: Into Darkness'. That was before Paramount released this picture labeling Zachary Quinto as Spock, Chris Pine as Kirk, and Benedict Cumberbatch as... John Harrison. This guy:

"In 'Space Seed,' Harrison was nearly suffocated to death on the Enterprise bridge by unfrozen superman Khan."

You know I am paying to see this movie, right? I'd kinda like to something about it. Do I even get a real Star Trek ticket when I buy one or would that ruin the surprise? Is there a theater behind the door I'm sent to or does it just lock me out in the alley?
