The Wii is a young console, so we cannot determine its 3rd party support for this gen just yet, that said; I've said and I maintain that it'll get a lot less 3rd party support than the market leaser usually does.
And, remember the first 2-3 years of the PS1's life; 3rd party support was less than brilliant to say the least.
For Nintendo, lack of 3rd party support will matter a lot less than it would/will for the other two, Nintendo is largely a software company and they have some of the planets finest inhouse developers.
N64 had very little 3rd party support, but I can't remember a Ninty generation with better games tbh.
