So I've been sending emails like this to Jeep a couple times a week for the last 6 months or so. If you want to see any options on the new JK, it wouldn't hurt to let them know.

I would like to express my interest in the JKL CRD for the US. We need a better offering than the abysmal 3.8L V6 from the Caravan. The 2.8L CRD would be sufficient for the 2-door JK in '07, and the 3.0L V6 CRD for the 4 door JKL would be ideal for towing the heavier "toys" often associated with the "Jeep Lifestyle".
The additional fuel efficiency is well worth the upfront cost over the life of the vehicle. The fact that the BlueTec is low-emissions is also a bonus, hopefully not at the expense of reliabilty. Further mileage improvements could be realized by investing in diesel/electric hybrids. They low-end torque of the diesel is ideally suited for powering electric generators even in small engines like the 2.8L CRD.
I would suggest using a hydralic assist system over the electric braking systems. From what I understand they electric-based regenerative systems are located at the wheels, which in a Jeep are a vulnerability due to water crossings. Hydraulic systems are not susceptable to water damage.
Also, how about having an easily snorkeled air intake for the Wrangler this time, possibly back by the passenger firewall? Rubicon models should have a higher axle/trans/xfer case vent that is connected to the engine intake to ensure these expesive parts don't "suck" water in when they encounter water after heating up. In a production environment this might cost an extra $15/vehicle - but it will save thousands in foolish repairs.
The swaybar disconnects, Stability and Anti-tip systems are indeed welcome.
Options...that's the future of SUVs.
