Just a quick disclaimer: I'm the person behind the livery concept marked as "arpdesign". This is NOT the new livery. I did that design purely on request of an aviation news website for an article about how some airlines could modernise their look.
My design is all over the net right now. It is true a Lufthansa 747-8 is in for a repaint with a new livery, but it will not be mine. Well, it better not as I was not consulted! lol. I want my money otherwise!.
I expect the new livery to only be a slight change to the present one. The cynic in me says they'll just delete the grey belly. That will save paint, which saves weight. It will also save on the down time for the repainting.
