Re: Mass Effect 3
Hopefully with ME4 they'll do something similar to what the Dragon Age team is doing with the Dragon Age Keep system. From what I can tell you'll apparently be able to set choices for what came before in the previous games without having to worry about importing any saves. Makes sense with the jump to next gen consoles.
KotOR II basically had you go through dialogue trees that told the game the choices you made in the original game.
