Will 2013 be the year without "Gangnam Style"? Psy said his performance on Dick Clark's New Year's Rockin' Eve would be the U.S. finale for the hit single. South Korean entertainers and stars of the video, Roh Hong Cheol and Yoo Jae Suk, were on hand in Times Square to share the stage with Psy and special guest MC Hammer. So what does the New Year hold for Psy?  According to him, his next U.S. mega-hit is in the works.  We'll be ready when (and if) it arrives. Do you think lightning can strike twice for Psy, or is he a one-hit wonder?
