I didn't like the previous film, so I'm not too upset at seeing him (apparently) not be on board for the third "reboot" film. Then again, for all we know, Into Darkness will bomb and there will be no third film anyway. If there is, then it'll be interesting to see what direction somebody else takes it in. I can only imagine they'd go with something along the lines of the previous film, given that it was an undeniable commercial success.
Kim: I'm detecting some weird technobabble.
Janeway: A possibly dangerous anomaly that we know nothing about?
Kim: Yeah. I suppose we should steer clear.
Janeway: Ha! Good one, Ensign. Take us in, Mr. Paris.
