Nintendo has now supplied third party developers with the information to access the Wiimote's internal memory and built-in speaker.
Of course, this will lead to better games, and more interactivity.
However, the Wii-mote's internal memory can only store saves for one game at a time. So, in practice, if a user saved their play style preferences for Metroid Prime 3: Corruption to the device, the information would be overwritten when they attempted to do the same thing for Excite Truck.
