Bootstrap 3 RC1 was released two days ago and from a quick look through the changes and the code, it all makes a lot more sense to me.
Here are some of the changes that seemed interesting to me:

3.0.0-wip branch to get the code or download it from http://getbootstrap.com.
The examples have been moved to a separate repository as well, as the team explained in the v3 pull request.
