Or perhaps they want to keep making games like Assassin's Creed 1 and 2 as well? There are ways of making money outside of the Wii (this is the biggest myth this gen) if you make an effort and I don't think any developer dreams of making only dance games.
What if you were a professional painter that was only allowed to draw stick figures? Hardly fulfilling. Most developers will probably want to both turn a profit and make different games.
