I've kept up with the rumors on this thing about as much as I reasonably can. This rendering is probably about as close to "that's probably what it's going to look like" as I've seen:
More or less looks like a DC100 with the updated headlight signature, with a few design changes here and there to make it fall in line with the rest of the brand (which all pretty much looks the same).
One item of recent concern is an article I read that quoted LR designers after the unveil of the new G-Wagon. It seemed they were scoffing about the redesign and how it did not change much, and how they wish they could unveil the new Defender at that same time.
If that means what I think it means, it may be a hard pass for me. Time will tell, though, and I'll keep my mind open. One thing that will tell me how serious LR wants to be with this is whether it comes with 18" or smaller wheels. If they stick with the 19" wheels, you can tell where their heart truly lies.
