Dynasty Warriors 8 is scheduled to release for PS3 in Japan in February 2013.
The release will bring three brand new characters– Guan Yinping, who uses a double-headed mace; Guan Xing, who uses dual wing blades, and Zhang Bao, who carries a Thorn Blade. Other characters will also reappear from previous games.
For Dynasty Warrior fans in America, the game will likely release in the states shortly after.
