I'm not a big fan of the post-credits scenes thing.
And I don't really care if they have something at the end that could be used to lead to the 3rd movie, as long as the story of STID is wrapped up. No cliffhangers, please.
NO NO NO! Cliffhangers. PLEASE!!! Means we get another Trek by the Bad Robot group. A fantastic TV and movie production company ( I am not listing this stuff again. Lost Fringe. Nuff said). ST3 with Orci directing and JJ producing. Yes PLEASE!
