So does the ESS than plug into the secondary battery? Isn’t the battery being removed linked to ESS? I know if you unplug it at the main battery it disables ESS? Just asking I am not sure how anyone justifies $4k for an extra battery.

It wouldn't be correct to say the ESS system plugs into the secondary battery, because both batteries work in tandem to provide the ESS system's functionality. But I do believe that whatever duties the small auxiliary battery used to do, the new full-size secondary battery will be taking over those same duties. We'll need for them to publish the specs to know for sure how they set it up though.
A fully loaded setup with the G-Screen and two new batteries is $1400 USD. There may be more money needed for a secondary fusebox and switches.

I've had Genesis dual battery tray in my JK for a couple of years now. It's definitely necessary, or at least comforting to run my ARB fridge when in the mountains for extended periods of time. This will be a definite upgrade on my JL.

Has anyone seen more news about this? I am really curious how it will work as the JL seems to have a variable alternator system which involves the onboard computer having an intimate knowledge of the batteries it's charging. I'm curious if they're going to have to add in something like a RedArc BCDC1240D for the second battery rather than using only a relay.

fwiw - the base price (on the JK version) is $479, not ~$1400 as posted earlier in this thread. source the batteries locally instead of buying theirs, and you may / may not need all the bells and whistles.
there's just a huge disparity between $500 and $1400 - I think @$500 it's a pretty good deal, even if I have to buy my batteries. At $1400, not so much.
my opinion anyway

That's not the system I wished they made...I was hoping they would build an isolator system that would allow the small starting battery to be isolated, so you can run your fridge and stuff off the main battery, but should it somehow become drained, the isolator would keep the aux battery alive allowing the jeep to start. This is a massive amount of excess weight that IMHO isn't necessary to lug around. In the JK, sure, but since the JL already has a secondary small battery which can start the vehicle, there is no need for a separate full sized third unit.

I am working on a DIY solution now like that. I managed to bypass the second battery thus far and have all operations run off the main battery, then I Tazered the ESS. My next step is to use one of the Aux switches in momentary mode to trigger a solenoid to reconnect it to the main battery if it needs a boost to start.. Then just add a conventional battery isolator to keep the aux battery charged.

Keep us updated on this. This would be the ultimate solution
