As discussed dozens of times before, the new car will be here in 2014 (probably 2015 for the US). So 2012 is a deliberate lie to sell magazines.
Also, there are no F32 spy shots yet so this artists rendering is off by a mile at best.
Essentially then, there's nothing here to comment on. There are better threads in this forum to discuss to the new engine and the end of production for the E9x, the end of the S65 V8, and the end to naturally aspirated Ms and BMWs in general. Each has been discussed multiple times before, at length.
A gen-u-ine BMW eff-eight-zero with them tandem clutches in the transmission and that dad gum sun roof on the top-a da cawr.
