Still Server will render the main page. Main page is " html + main content that user and search engine wants to see". Because the search engines need to index this page ( meaning the URL ), so the main content must be same, unless it is a private page. Also the browsers are designed to render html from the server. HTML5 brings in a lot of dynamic features, but the main feature is not going away.
