One of the companies showing support during Sony's PlayStation 4 press conference was Capcom. Yoshinori Ono hopped on stage to reminisce over PlayStation's past, and then got right to the main event. Deep Down (working title) is in development for PS4, and the clip they presented does a good job of showing off Capcom's new Panta Rhei engine.
