For all you folks with an automatic Cooper S on order, here is what your steering wheel will look like. Both paddles operate in the same fashion, push to downshift and pull to upshift. As mentioned last year on MotoringFile they mimic the design and operation of the SMG paddles in non-M BMWs*.
You can read all you ever wanted to know about this new transmission in this previous MotoringFile article: MCS Automatic Debuts.
* Please note that this is not an SMG transmision but a normal automatic.
