I agree, the Exile would be a hard thing to put in depending of what people put in, its gona be really hard if this series progresses towards K3, because it was pretty confusing in K2 as it was, you know - Revan is DS, Revan is LS choices, either way it greatly affects the game, now if there is a K3 you'll have to choose both Revan and Exile so its going to be a complete jumple up, there will be numerous things which happen during the game, and many, many resolutions and endings.
So to perhaps resolve this issue, instead of having all this freedom with the choices, maybe it has to lean more towards the canon aspect. As Plano Skywalker said, Revan is flexible, because either way he ends up going to the unknown regions to fight the true Sith. On the other hand, we do not fully know the ending of KotOR2, nor what truely happened to the Exile, s/he could have either a) gone to find Revan to fight along side(LS) or b) stayed at Malachor V? (DS)
Maybe when it comes to the Exile, they should keep it canon, ie. Canon side, but not gender, thats not really an issue with gender. Keeping Exile LS, and having Revan either side.
