Audi is so far ahead in interior design when compared to the competition, that the current generation A8 which was released in 2002 has a better interior than the completely redesigned brand new S-class which came out in 2007 and even the BMW 7-series with its horribly dysfunctional i-Drive.
Even Lexus which has been known for their quality interiors fails to set the standard in terms of fit & finish, layout, ergonomics and feel when compared to Audi.
What would you like to see Audi do in the next generation A8 that comes out in 2009 or 2010.
I expect the following:
1. A head-up display that is similar to BMW's but better
2. THE SAME MMI system because it is still more intuitive than Mercedes' COMAND or i-Drive from BMW
3. Nightvision w/ heat sensors
4. Increased legroom to surpass the 7-series
8. Heated, air-conditioned and massaging REAR seats
9. Back-up camera
10. MORE wood (I don't know if that can be possible)
