So, it won't be a true "Full Size Jeep" in the sense that it's not the SJ. But it will be "full size".
Anyway, Road & Track released a short article on what they know about the upcoming full size platform.

Bottom line, they don't know a whole lot. They certainly aren't saying anything new that hasn't been speculated before. It's still going to be a luxury marque that targets the high end market like the Land Rover and Mercedes territory, as well as Cadillac and Lincoln.
Plug in hybrid will probably be available since everyone is going that direction. But they speculated about a "hellcat" type version as well, which will surely cost more than my first house...
Anyway, I would very much not get my hopes up about this having anything more than a token cosmetic throwback to the SJ line. It will be a street machine that can handle the dirt roads out to country estates and that's probably about it.
