A Shakespeare tragedy. What's new?

Being a Shakespeare tragedy, the audience is safe to assume that someone is going to die. Like in Shakespeare's Julius Caesar, Mark Antony plots to kill Caesar which eventually leads to the death of Caesar. Since Othello is the protagonist, I think Shakespeare brilliantly foreshadows his death through some of his hidden clues. Not only does the play bring on a feeling of hinted sadness, the audience gets a feeling of suspense about what Iago is going to do next to plot against Othello. At the end of each act, Iago speaks alone which alludes to the fact that those are his true feelings (I.iii.364-384, II.iii.345-351). As a reader, I have come to anticipate Iago's words to see how they will advance the plot and judge if his plan indeed will work. I believe Othello, Desdemona, or Cassio will end up dead and Iago will eventually get what he's been working towards.
