Well, the R8 delivers on more complex tracks like HH and is more fun to drive, but in more road-like conditions like NBR the gain over RS4 is really minimal (5s in nearly 21km is nothing) - as was to be be expected all along. Where is the surprise?

Hyping the RS6 in the wrong places does it no favours - it will surely deliver as an all-round road going package like the RS4 and I will get one if and when it does. However, ceramic brakes will not be standard and they will not save a 2 tonne monster with 60% upfront on the track anyway and you can forget 0-200 km/h in 13s when you do the power-to-weight math and account for the likely 20% transmission loss...
