I heard some changes are coming for the 2012 model year:
- redesigned gear shift area - now will have pop up gear selector like in the RRS.
FWIW, there is no such pop-up selector on the Sport. Such a Jaguar-like gear selector has only been introduced in the 2011 V8 diesel Range Rover abroad, petrol engines still use the good 'ole fashioned shifter. At least for MY2012, it appears the Sport is still going to be equipped with the shifter of earlier model years (a "Quick Guide" for the 2012 RRS recently popped up on TOPIx), so I'd be surprised if the LR4 was equipped any differently.
However, there will likely be improvements made to infotainment + navigation systems and related touchscreen interface (including a possible hard drive storage system for music / CDs.) Not sure about the 8-speed ZF - the Quick Guide doesn't say obviously, and there is no official info out there yet on any 2012s from Land Rover, other than press releases for the upcoming Range Rover Evoque. The 8-speed tranny may also be something reserved for diesel versions, as mentioned above this transmission is already in use on the V8 diesel RR in ROW.
