I'm pretty sure that if he's alive Zaalbaar is with Revan, meaning so is Mission (same life assumption).
Carth, if you are LS, is with Revan. Otherwise he is probably dead or stranded.
Bastila is with council or Revan.
Hk will always be with you and I don't think you'll kill him. Same with Canderous.
Juhani is the same as Bastila+the dead option.
Jolee is Revan, dead, or doing things his own way (we have no idea where he is if he decides to go his own way like he probably did).
Trask is dead (had to put him in there).
And Revan himself is gone.
Anyone else think that a good part of the game will be seeking out jedi who are still alive, and banding them together to help you? That means that you probably (as much as I dislike it) search for Revan. Or at least gather clues through datapads and the like.
