MINI hasn't annouced anything technically. They've internally told their dealers an automatic transmission with paddles will be available Jan 1st onward.
I don't think anyone has ever said it will be an SMG, and everyone in the know says normal automatic.
Also, the internal PDF:
http://motoringfile.com/files/2005_Individual_Specs.pdf on the second line says 'Automatic Transmission' I don't know anywhere where BMW has called the SMG an Automatic transmission, and on the first line, they specifically say CVT.
Sure I could be wrong, but no one has said anything to support the SMG besides hoping for it, so I think its highly unlikely, hence I've been working with the assumption that its a normal auto, and thus have views on it. An SMG is totally different, and from my view, irrelevant on an S unless something changes in the plan for options.
