I don't count the Wii Wheel or the Wii Zapper because they're just shells. The only major peripherals Nintendo released for the Wii so far are the Classic Controller, Motion Plus, the Balance Board, all of which Nintendo supports with peripheral specific software (I include VC titles). None have been kicked to the curb as of yet. My point with Move is that most titles will also use the Dual Shock 3 and the ones that don't are probably available on the Wii in some way, shape, or form. Thus, I'm given no reason to shell $80 for the peripheral plus the Playstation Eye. That was never the point of the console.
And I know what to expect from Ghost of Sparta, doesn't mean I still don't want to see it.
