2011 C63 Facelift leaked (offical). MCT confirmed
1. Real 3D displays (which shows 3 dimensional pictures without need of wearing 3d glasses).. you won't find these in nowadays cars.
2. "Split Screen" Displays as MB is optionally giving you in actual S class. Here the driver and the passenger got 2 different views (depending on the angle of view). This is like the pictures you sometimes have in your Kellog's cereal package :-) But it has nothing to do with 3D.
3. You can give HMI Icons and pictures some kind of effects like shadows and reflections from different light sources. Try Google Search on "3D icons" and it will give you a guess what I'm talking about. This is what you now get in the new CLS and the C class instrument panel. So you can say it's 3D (which it isn't really) but actually it's "just" nowadays fancy icon style.
It might not sound overwhelming but I can tell you it's a long way to get such icons into a car instrument panel because of a mass of regulations in a lot of countries the car is meant to be sold.

I have driven California the up shift and down shift speed is OMG amazing.
How about the incoming C63? I will trade in my 7G C63 for 2012 C63 if it performs like regular dual clutch transmissions.
At mean time I can only YouTube E63's clips.
