Same reason why a wiimote for the GC wouldn't be as great as the Wii itself. If you "train" and market your fan base or a long time to play with a controller and then throw in a new peripheral that has little software support and poor marketing, then the peripheral's success wouldn't be as high as one that had came bundled with every console and marketed as a "unique type of gaming" from the start.
