Ken McKown writes: The PS Vita was supposed to revolutionize handheld gaming. The system has two analog sticks, making perfect for shooters and camera movement. When Activision first announced a Call of Duty game was coming to the system, most of us called it right there. Unfortunately, that was pretty much the last we heard about the game until it launched. Rarely had anyone seen footage, and little was known about its structure. Now we all have copies in our hands, but are left wondering how someone could mess up a perfect formula this badly.
