The above statement holds true. They have done exactly the same thing with the new GS-F. They have removed the HUD option altogether since it has the F Sport moving dial thingy.
The GS-F will also be driven in Vienna, but they have it in white. The same car was showcased in Barcelona and it looks terrible. The IS F -Sport in White looks stunning in my opinion, as it doesn't have any big air intakes etc . The GS-F on the other hand is full of them and will be very colour sensitive . I'm intrigued by the GS-F. It looks great in Ultra Blue but the switchgear that was paraded in Detroit is exactly the same as the current GS, albeit with a back button for nav.
It will be interesting to see what it's really like in real life .
