I'm assuming what you are loving is that by using Nova and the JB theme you are going for a stock JB appearance, but what I'm saying is that when the JB update comes out you still aren't going to get the stock JB experience because it won't be a stock JB update; it will be JB with Samsung's TouchWiz skin over JB, just like it is currently TouchWiz over Ice Cream Sandwich. When the update comes out you probably won't notice much aesthetically. Therefore, if you love your current setup you are going to have to keep using Nova, and even the JB skin if you like the icons, because otherwise you'll have the TouchWiz/Samsung icons.
