MB Passion says the new model will be the ML Coupe, with internal code C292, named similarly as the S-Class Coupe, and not be called the MLC. The production is to begin in 2015, as expected. 
They also remarked the ML Coupe appears beefier to them on the Autobahn than the present ML. MB anticipates Europe not to be a primary market according to Dieter Zetsche.
That seems to agree with MB Australia's recent remark:
"McCarthy said Mercedes-Benz Australia CEO Horst von Sanden had seen the [...] production car in the flesh and described it as a “ripper” that was “very close” to the concept."
