Yeah, the undercut is deep. This is the reason why was surprised to hear comments that coke bottle was not quite as spectacular. As I wrote before the design philosphy is obvious and RBR has gone a long way in packaging all the components away from the area right ahead of the diffusor. The RB9 had already the cooling outlets in a similar position, now they are bigger and wider which gives a false impression on the shape of the coke bottle if you look at it from above.
Thanks for posting all those high-def pics =D>
