Very very speculative. I (nor do most of us) have no idea what's gonna happen throughout Phase 2 or for Avengers 2. If Marvel decides to go down the Civil War route, does anybody think that Iron Man 3 would set up Tony Stark's character such that he would now cooperate with the government? I hope they don't go down this route. Going pro-Shield/government/registration totally contradicts MCU Tony Stark's personality.
