Well, when you had the Eleventh Doctor basically running around in the sixth series, trying to avoid his death... I don't think they'll treat his regeneration as an imminent one.
At least, I hope they won't.
"Spock...?" Kirk said, whispering.
"I am... most pleased to see again, Captain" Spock formally replied.
McCoy shook his head in disgust. "Oh, for crying out loud, Spock. Its been eighty years!"
"Seventy eight point four years, Doctor."
