Here are my personal predictions - feel free to add your own: 1- Additional sound insulation making the S even quieter than it is now. 2 - More advanced air suspension options that iron out small pavement irregularities. 3 - Continued gradual mprovements in the quality/durability / feel of interior materials - gradually raising the interior "feel" toward that of the Germans and Lexus. 4 - Second generation of the premium seats - getting closer to the Germans and even more comfortable. Extendable thigh support, articulating back rest, massage functions, etc.
