Exactly. Back to my original idea, if they had flown in to Nero's space-time sphincter in the first movie then perhaps in the second movie they would emerge in the Mirror Universe. Have a movie of Enterprise vs Evilprise, so to speak.
Maybe the wormhole sends them to the Mirror Universe in the future
. That way we could get a Shatner cameo as older Mirror Kirk. You can't tell me that Pine vs Shatner wouldn't draw legions in to the theaters.
Come to think of it, that premise would actually make the title Star Trek into Darkness
somewhat applicable to the plot. On multiple levels, even.
