I want to hear about some of them, but I don't really care for it to be a huge part of the game. Perhaps like what GhostofAnakin said for the minor characters like Juhani, Mission and Jolee, but maybe a small event for the likes of Revan, Carth, and Bastila.
I won't be disappointed if we don't hear anything because our new character will have an all new crew for us to gain interest in.
