As far as comparisons go, they're not even the same vehicles. The JL is a 100% clean sheet approach.
Same situation with the new C8 Vette. A completely new car unrelated to the C7. You cannot even test drive one - dealers want deposits, then you take delivery sometime after Dec.
Tech is what is driving the price increases. Not just adaptive controls, but also finer tolerances in engine, trans builds, etc.
The last year C7 will be mark down a lot. I got my 2013 C6 Grand sport for $15k off, because the local dealer wanted all the C6 gone. That same dealer has mess load of C7 on the lot.
