This post from Kotaku (more pictures there) explains itself:

This new batch of Soulcalibur IV screens features the next-generation look of three fan-favorite fighters! The quick and formal Xianghua, the brutish Lizardman, and the man with the giant stick, Kilik! Kilik’s name is generally either greeting with a whooping cheer or a pained sigh, as for every fan of his powerful Ling-Sheng Su Style there is another player sick and tired of having a giant rod slammed down on his skull. Kilik is certainly looking formal this time around, isn’t he? Xianghua still dresses as skimpy as ever, and Lizardman is still part lizard, part man, but Kilik seems to have gone and gotten himself a real job in-between games. Good for him!
