There are too many possibilities to say what will happen for sure in ME3. I'm sure that if Shepard didn't survive Mass Effect 2, the Illusive Man probably made a clone of him; he did have access to his DNA for two years. I also think Miranda's father will make his screen debut. Legion may enlist the aid of the Geth while Tali could take her father's place on the Quarian admiralty and lead the Quarians into battle. Alot of things are up in the air about what could happen in ME3, since the experience will surely not be the same for everyone.

One a side note, I just have to point out ralok's prediction on a romance with Legion. Legion is a machine and stated that he understands emotions but he doesn't feel them. Something that doesn't feel love is not going to fall in love, that's something that will definately not happen.
