We all were expecting to see the BMW M4 unveiled at the 2014 Detroit Auto Show->ke222, but it looks like BMW ->ke178 has a little surprise prepared for us.

From what we're hearing, both new M Series models will make their online reveal this on December 12th as a part of a DLC package for Gran Turismo 6, which is now available for PS3->ke3735.

We already knew that the BMW M4 Coupe will come to life in the GT6. According to an announcement made by Sony, the M4 "will be made available through a free update shortly after the release of GT6, allowing car enthusiasts around the world to drive it before it arrives in BMW showrooms" in 2014.

Since the model will be revealed in GT6, it would make no sense for BMW->ke178 to keep it a secret until January, so we'll have the first details on both models this Thursday.
