If you like Qunari I have a good information for you. On his Twitter, David Gaider has posted that in the second tome of the comic featuring Alistair adventures we will see Sten. Yes, the same Sten we could have freed in Dragon Age: Origins. I don't know what role he will play in Dragon Age: Those Who Speak but I think that David Gaider would not let Sten to be merely an ordinary bystander.
