I wanted to address the burning question: how will Mandarin's rings be used?
The fact that the trailer shows a shot of them before we see his face leads me to believe that they will be important. However, both Shane Black and Kevin Feige said that Iron Man 3 will be more grounded and not have anything to do with aliens or magic. My question is, will the rings have offensive and/or defensive purposes like in the comics, or will they merely be for show as a nod to the fans and to symbolize the Ten Rings organization? I want to hear what you guys think.
