I'm not going to worry about it.
every single new model of the wrangler has been better than it's predesessor so until they actually make an error I'll believe the new wranglers will be better.
lets review a quick history:
1975 CJ-5 was too short and rolled too easy so they made a longer CJ-7 AND put a V-8 in it!
1833 made the axles wider and killed the CJ-5 so they didn't roll so easy (again)
1987 gave the wrangler a hydroformed frame and galvanized body tub. they also moved the speedo from the middle of the dash and widened the axles (again!)
1990 fuel injected 4.0 replaced the horrible smog choked carb on the old 258
1997 the TJ. good tranny, good t-case, larger axle u-joints, good engines, air bags, coil suspension, strong frame, solid axles. The TJ is miles ahead of the YJ in every way.
then the TJ rubicon...
then the JK. crappy drivetrain but finally HP axles in the front and most JK's have a dana 44 in the rear. rubicons got bigger axle shafts and larger u-joints (again)
so again, every wrangler has been MUCH better than the ones before it. In fact, the newer jeep you buy the better it is and that has been true since the 70's.
relax. see what they make. I bet it's sweet.
