If this trailer is any indication of things to come, get ready to watch The Mandarin (played by Ben Kingsley) make Tony Stark suffer in "Iron Man 3" and get ready to see a lot of fireworks. Aside from this being a must-see movie of 2013 I also noticed that Ben Kingsley pronounces "terrorist" kind of similar to how Charles Barkley pronounces "terrible." "Some people call me a TURRURRIST..." 

According to Marvel's YouTube Page:

In Marvel's "Iron Man 3", brash-but-brilliant industrialist Tony Stark/Iron Man played by Robert Downey Jr., is pitted against an enemy whose reach knows no bounds. When Stark finds his personal world destroyed at his enemy's hands, he embarks on a harrowing quest to find those responsible. This journey, at every turn, will test his mettle. With his back against the wall, Stark is left to survive by his own devices, relying on his ingenuity and instincts to protect those closest to him. As he fights his way back, Stark discovers the answer to the question that has secretly haunted him: does the man make the suit or does the suit make the man?
