To me Cumberbatch's Khan was more comic book than a throwback to literary figures as Khan was in star trek II. the New Khan is decidedly not Ahab, or Lucifer from paradise lost.
You don't see him being this really intelligent guy where are all his books and he does not quote from classical literature.
He is more like an evil Superman who cannot fly.
I am not the least bit interested in seeing him in Bond or in star wars. Especially as a albino sith in star wars VII, VIII, or IX.
