I bet it will be something like the forthcoming Jeep Recon. Assuming the teaser is close to real you can see light coming in through the roof a bit on each side. Just a guess.
Looks like it might have a panoramic roof. Possibly removable? Similar hood trail site feature to show the inside tire edge. Looks like a bench seat in front but that would surprise me.
My guess is close to but slightly smaller than the Wrangler and/or Bronco. That would be closer to the Scout heritage. The Traveler would have been larger. As would the Travelall
