Third parties have rarely made an effort on the console since it launched, and Nintendo has essentially given up on it [Wii] already (they don't really have the resources to hold up two consoles without any help) as such there will be nothing to hold the console up.
Maybe if a significant number of Wii's start failing a-la PS2, people will be picking up replacement hardware, but otherwise it would have to rely on the few people who like to pick up consoles cheap at the end of the generation.
