There is lots of room for interpretion. Prequels and sequels are being planned like the the First Contact War and rise of Cerberus. I actually hope the'll add packs where Mordin and both Virmire survivors can live and Shepard's origins combine. There would be 3 Shepards: the mother, the brother John (who I'd prefer as the main character) and the sister Jane.
