I could be wrong, but thought I read/saw somewhere a possibility of a front-mid-rear top. Instead of the current t-top system.
I can see the power soft top doing ok from factory actually. Though 5k is steep for a button.
With all the new engine options, I may wait a little longer to make sure there are no major bugs. But I can't see not getting one sooner rather than later. ENVY needs a brother or sister.
Just my opinion, I think the JL is going to kill it in sales. It's going to have so many features and interior comforts that will appeal to the masses. May not carry every feature off-roaders want, but you need volume sales for good aftermarket support.
