It does seem like the logical extension or projection of the Boxster design to a coupe, also taking into account the spy photos seen to date. I doubt the new Cayman will turn out to be as much of a surprise at this point as the new Boxster was, with its CGT like doors and side intakes, and its rear lights with built-in spoilerettes.

I don't know if RC knows something he's unable to share, but it seems to me that at this point, we're talking about details, such as the spoiler treatment, and the rear light treatment. It is clear from the spy pics that the car will remain a hatchback, and that it shares the new Boxster doors (camouflage similar to Boxster camouflage). Thankfully, it looks like the problems (imo) with the overly curved bubble roof and rear hatch have been addressed in a subtle but sufficient way.

I very much doubt that we are going to see a notchback like the Dino or the 914. That would have been an interesting surprise...
