Must say that aesthetically, it won't be a residuals disaster for the earlier cars - doubt if they will modify the interior much this time either? My guess is that they will be trying to keep their re-tooling costs as low as possible in this uncertain economic climate? As posted above, expect some improvements in the ICE/Tech department?
On fortitude there is another one picture also included showing masked interior. If you look carefully, however, you can spot new MMI controls, similar to these found in in facelifted A4 (as expected). So does not look as major visual change inside, but function-wise quite significant update.
