Definitely want one, but I think 75k is a little steep. I'm taking it with a pinch of salt though, I don't know how a customer can be invoiced for it already if Jeep hasn't officially announced pricing yet. It doesn't make any sense for it to cost more than the TRX especially given the TRX has the supercharged motor and the Wrangler 392 is a naturally aspirated engine. The TRX is a bigger body, heavier chassis, stronger axles, just more of everything.
On other FCA products where you can get the 3.6 pentastar, 392 V8, and 6.2L Hellcat motor, you can get a pretty good idea of where the costs should be. I saw estimates putting the Wrangler 392 at around 65k previously based on educated guesses and at that price, sure. I'm interested. 75k seems to be a big ask for what you're getting really.
Will definitely buy one at some point. It's something I've wanted for a very long time. Where Jeep puts the pricing will determine how quickly I get my hands on one, and whether it's new or used.
