yeah I hope they will. I mean they have to. there's just so many unanswered questions. I mean, just the whole Mandalorian Wars. That's where Revan and Malak turned to the dark side.
In Kotor 1, when Revan asks Canderous why the Mandalorians attacked the Republic in the first place, Canderous says "The Sith came to us with and offer we couldn't resist".
In Kotor 2, Revan is off to find the True Sith. And when you talk to Carth (if you talk to Carth), he says something about that maybe it wasn't the Mandalorians idea to fight the Republic in the first place. And the Exile goes after Revan.
Kotor III is bound to happen, and I think that it will be Revan, the Exile and the true Sith. Maybe you find out the real reason to why the Mandalorians attacked the Republic in the first place. And it will all end with an traditional Republic vs. Sith fight. That's why Revan wanted Carth to keep the Republic strong.
well, that's my theory anyway.
