My guess:
Centre diff kit conversion/upgrade. Looking at Savoya's buggy with the centre diff, it had a new top deck, new centre(rear) moulded slipper mount and a new centre rear CVD (68mm).
Maybe some Smokem like shock towers with the extra camber holes.
Praying for metal bevel and pinion gears.
My bet is it'll still run the composite spider gears and no shorty conversion until 2016.
They will market the buh-jaysus out of it though if the T4 '15 is anything to go by
