Does anyone think the Wii will see add ons using its ports?

I've already theorized a housing that allows you to use a modified Wavebird receiver. that fits flush with the edge of the Wii. After all, people still plug gamecube controllers into the gamecube ports, so why would they give you a memory expansion that would take up one of those spaces, when they have the USB ports already available?
