Note the four hotfixes required for SharePoint 2013 RTM Installation
Sometimes, it pays to read the manual. I happened to glance at it while I was doing my installation last night and noticed that there are four required hotfixes you need to install prior to installation of SharePoint 2013 RTM. You install these after installing the prerequisites via the newly named Microsoft SharePoint Products Preparation Tool.
