I think that the lack of polish on many of the titles simply has to do with the fact that the majority of third party developers, particualrly the western ones, have not had access to final or near final dev kits. The IGN article on Red Steel claims that Ubi did not even recieve a dev kit until late march, and until then all development was done on a PC. It would be likely that over the next few months, the gameplay and controls will be tightened up via internal testing and better graphical effects, textures, and polycounts will be layered in as the hardware improves.
