I've already seen quite a few of the new 3er wagons out in the wild with their zebra stripse(camo) coving the car's rear sections. Only a few have been M340i's though. It's quite hard to tell now that all models have dual exhausts pipes.
A BMW AG friend of mine just got to drive one of the M340i prototypes... he said it's AMAZING! Actually... he said it is THE machine!!
