I am not excited about the next gen Wrangler, but I am interested. I am not brand loyal, I buy what I like, and I have owned more Jeeps than any other brand (unless you combine Chevy, Pontiac, and Hummer as "GM" then GM wins). Of all the rumors I've heard, they all sound great to me with one exception, going from body on frame to unibody. I know, unibody can be lighter, stiffer, and stronger but I have this old school mentality that says if you wheel a unibody enough it will develop squeeks and rattles much worse than a body on frame. It's not fair for me to compare my old lifted high mileage Cherokee to a new Wrangler that hasn't even come out yet, but wheeling a topless unibody just sounds like an invitation for squeaks and rattles.
BTW, the concept vehicle on page 1 is a Hurricane, not a Wrangler concept. Some crazy 2-seater with 4 wheel steering.
At this point I'd say there is less than 1% chance I'd buy a new gen Wrangler when they come out, but I could see myself picking up a used one once my kids are out of school.
