I'm still reserving judgement until I see it in person, but I don't like the sloped back roofline I see in the pictures.

The engines are interesting, they seem to be going for drivability not headline horsepower. The bump in torque should have a big difference in driving feel, especially with the reduction in weight. The Cooper will be pretty fast in its own right and the bump up to the Cooper-S doesn't look that big. I'll be interested in seeing what they can come up with for a JCW.
