Yeah, I think showing "the near future" during Khan's reign could be a great opening scene. They could show him as a big infamous dictator or someone pulling the strings.
In any case, I'd want a "three-dimensional Khan" this time, stealing everyone's show and not being tricked so easily.
As for the Klingons: I hope JJ takes the liberty to revamp them completely. I would more TOS-like Klingons (in behavior), without 2309 Blood Wine and honor crap, but then their appearance should change considerably, so that we would not be wondering about the same old TNG-looking Klings "acting out of character". If the JJ KLings are just the old TNG Klings, he just might use other aliens.
