To be honest I don't see a way how the devs could create a crew that will not repeat time and again what it is doing. The are only a number of spoken sentences available and that is all the AI guys can say. It's impossible to have any longer conversations without repeating them time and again on a long patrol.
I guess it will be approached like it was in Elder's scrolls IV Oblivion with one AI guy adressing a topic and the other will pick randomly one answer out of a set of possible answers.
But maybe we will all get surprised with something really new.
