Sending you PR to check current state and the progress on the matter. If you find necessary, steer me in  the right direction. Generally it takes more time then I originally comprehended.
 
This is still far from being finished, but should be during the week.

Currently, I am in process of moving contend around to fit the flow properly and newly added primer. During the process some content should be removed. 

In the end [MVC section](http://addyosmani.github.com/backbone-fundamentals/#mvc) should have this outline:

* Smalltalk-80 MVC
* MVC Applied To The Web
* MVC In The Browser
* Simple JavaScript MVC Implementation
 * Event System
 * Models
 * Views
 * Controllers
 * Practical Usage

Let me know what do you think.
