[update] Here's a post on Roadfly from someone who claims to have talked to a BMW employee that was assigned as the liason for the development of the JCW package for the MCS. Some interesting stuff if true.

From MINIUSA:

Woodcliff Lake, NJ March 3, 2003…. At the 2003 Geneva Auto Show, MINI announced an exciting enhancement to the MINI Cooper S for the U.S. market – the John Cooper Works package. The exciting 200 hp. Cooper S package will be coming to our shores this spring.

Developed by the legendary John Cooper Works company, the unique warranted package will be sold exclusively through MINI dealers and will include a reconfigured cylinder head, uprated supercharger along with special engine electronics and a performance rear silencer. This enhancement takes the regular 163hp MINI Cooper S to over 200hp. Detailed U.S. specifications and pricing will be forthcoming.

I imagine the official pricing information will come out at the NYC auto show but I'm guessing we may here something before then. You can find more details in this previous post from last week.
