Does anyone know what changes will be made to the 2014's? I have seen comments that the climate controls buttons will be changed to digital like what is on the new E.

I just ordered mine and confirmed the dealership knows about the following (however, they won't know any others for a few weeks):

-Diamond Silver Metallic replaces Pearl Beige Metallic
-Heated/Cooled cupholders as a stand-alone option
-Parking Assist Package (includes Surround View Camera and PARKTRONIC)
-SPLITVIEW as a special order
-Introduction of Sport Styling on ML250 BlueTEC and ML350 (previously only available on ML550)
-On/Off-Road Package moved to special order
-Polar White replaces Artic White

I have pricing for everything that is available since i just ordered mine on the 21st.
