Here's some info from one of our developers:
The template cookbook that has some code for the AJAX Add to Cart that is used for the mini-cart in newer themes. The newer themes combine this with the Local Storage to have the cart/product information used to display the mini-cart. This code snippet has my original version of the ssAddToCart plugin and I think I have updated it a bit recently (in the last year or so). The newest version is found in the template/publish files and is called ssaddtocart.js

Basically in order to see a fully functional mini-cart using the AJAX JSON cart they would need to look into the code for the newer themes.
