A Wikipedia (via digg) entry lists all Nintendo Wii games that have been announced by game developers. Several of them are only rumored.
Currently the page lists 151 games for the Wii. Many of them have no release date or even miss the final title. All listed Wii games have a link though to the source. There is also a list of all known Sony PS3 games on Wikipedia.
If you have not seen the video promos on the Nintendo Wii site you should definitely watch them. Digital Battle compiled a list of 10 Wii game play videos from the E3 2006. See also our comprehensive Nintendo Wii report.
