Khan or not Khan? Cumberbatch continues to tease us about his Trek 2 role

One thing that can be said about Benedict Cumberbatch and his role of John Harrison on Star Trek Into Darkness is that the British actor has the uncanny ability of keeping quite mum on the subject of a certain Khan …

Actor Benedict Cumberbatch, who will play the villainous John Harrison in J.J. Abrams’ upcoming Trek sequel, is still remaining tight-lipped about whether the name of John Harrison is only a front for the more exciting or sinister figure of Khan Noonien Singh.

In an interview to be found in the May issue of Australia’s FilmInk (and put up by Trek Movie), Cumberbatch talks about his villain John Harrison (even skirting around the interviewer’s blatant attempt to make Cumberbatch reveal whether he’s playing Khan) as well as his iconic roles of Sherlock Holmes, Smaug (and the Necromancer) in The Hobbit and Harrison in Trek.

You’re playing a variation on the villain, Khan, played by Ricardo Montalban in 1982′s Star Trek II: The Wrath of Khan?
"Umm, I play a character called John Harrison. I can’t say more."…
Sherlock Holmes, Smaug in The Hobbit, and now John Harrison. Are you burdened by these larger-than-life characters?
"I do feel a bit disconnected from reality! I go into an audition, and I don’t think about the consequences of getting the job; I just worry about trying to. If I woke up and thought about how much hate there might be for a particular decision that I’ve made about a particular huge iconic role that’s dear to many people before I got my dirty hands on it, then I would not sleep at all because obviously that way madness lies. You can’t please everyone, and I’ve been lucky enough to work with people with great taste. I’ve trusted them, and good things come when you trust people."

What do you guys think? Do you still believe Cumberbatch is playing "a variation" of Khan, or that John Harrison is the definite name of Star Trek Into Darkness’ big bad villain? At this point, do we even want John Harrison to be Khan?
