I received confirmation from my dealership's Sales Manager this morning:
"BMW NA as of November 9th came with mid -year production change which is effective January 3, 2013 and soft close doors has become a stand alone option."
They gave me the option of passing on my GC, which is now on a boat, and re-ordering for a January/February production slot. While I'd like soft-close doors, I'm going to stick with my current order and just bitch about it for the next 24 months. Ha.
