They should definitely spend it on getting more quality games. Buying a developer would be a big help because 1st party is Nintendo's trump card and they could use more quality 1st party titles. But even more important would be building the best 3rd party dev kits and relationships possible. That would be the key to making the Wii truly dominant.
I think a theme park would be outstanding in the long term, as they have the franchises to become another Disney but theme parks of any serious quality would be a LONG way off.
