It's funny reading all of you argue over the suspension possibilities, but if you ask me I'm more upset with the fact that the JL might not have a removable top. I could eventually get use to a different suspension but I could never live without the freedom of driving a completely open air Jeep.
Things seem to be changing a lot lately so who knows what the end product will be but, up until recently, I believe the plan was to have 2 different versions of the new Wrangler - one with a non-removable top and one with. This would be no different than a Mustang or Corvette that comes in both a fastback and a convertible.
