First off, I'm a 3rd party developer.
The most attractive thing about the Wii is accessibility. It is fairly inexpensive to develop for. Developing for the 360 or the PS3 requires a huge team of artists as well as quality graphics engineers. You really don't need that with the Wii.
I've worked for Sony before and worked on a "next gen title", and the budget just skyrockets with the artists and tech required to pull of something that you would all consider next gen.
Small developers will go for the Wii.
