The SDL Tridion Reference Implementation has been released and announced on SDL Tridion World.
Per Bart Koopman, the SDL Tridion Reference Implementation is "an MVC web application (v1.0 is released as ASP.NET MVC 5), with CD side Templating. It uses DD4T to serialize the data from the Content Manager and is further designed to keep the web application independent of its "Content Provider."
Congratulations to Bart, Will Price and everyone that worked on (and sponsored) this reference implementation! Questions about it are welcome on Tridion Stack Exchange.
