Honestly, if they announced a Pokemon MMO for Wii owners, I think it would be scary huge. That game has almost a bigger cult following than Mario games. It could even be considered a WoW competitor for mass appeal.
Only problem is Nintendo is "anti online evil", it would be so limited. That wouldn't allow you to do talk to anybody directly and massive filtering system to protect against online child predators and online game "rude" behavior.
