Good analysis--I agree. I don't think a Star Fox game would require it, as the 'mote on its' own already has good tilt sensors. However, it's a very likely story, as Nintendo recently stated that they have ~100 games in development. Granted, that's split between Wii and DS, but given that very few of those games will be coming out before M+, it's pretty much a given that many will take advantage of it.
