The S appears to be getting a different interface than the SE, Autobahn and R that has physical buttons. You can see it on the configurator, but I haven't seen any real world pics of it.
Interesting. I checked some of the ROW sites and dealers but none of the GTIs or golfs seem to have that setup. Also of note. It appears the base golf (where its sold) has physical steering wheel buttons as opposed to haptic. Definitely an upgrade i'd consider assuming plug and play.
