No, this is not about a new extra value meal from your favorite fast food restaurant.  In order to accommodate different requirements and download sizes, a new edition of Express will be offered alongside Express with Advanced Services, about a month after the core edition comes online, called Express with Tools.  Like Express with Advanced Services, this will come with a slim version of Management Studio, as well as PowerShell integration and Sync Services (in the basic Express edition, you can get these as well, but they are separately downloaded/installed).  Express with Advanced Services will be the only edition to include and support Integrated Full Text Search, Reporting Services and Business Intelligence Development Studio.
