I think once the kinks are worked out, the Wii will be THE system for first person shooters. Right now Red Steel and Far Cry Vengeance are showing it's viable, though they have their own problems. I think when Metroid Prime 3 comes around, we'll see if the Wiimote can really handle first person gunplay superbly or if the dual joysticks are still the perefered way of playing it on a console.
