Dude. If nintendo realized you wanted an old school controller, and made one. then the wii would suck. there would be no draw. the controller *IS* the wii.
You can guarantee there will be games out in the future that REQUIRE classic controllers. Super Smash Bros will reportedly require classics or GCN controllers, and you can count on lazy developers dropping the latest movie tie in games on all 3 systems forcing classic controller use on Wii.
