Re: Who is John Harrison (Possible SPOILERS or Insane Babbling)
There's also a scene in the Japanese trailer that seems to be an homage to Spock and Kirk's final scene together in TWOK. Personally, I suspect it's neither Khan or Mitchell and the homages are just that - homages.
I'm still hoping for Garth of Izar.
