In these situations. There are typically 2 viable courses of action as BMW does not respond well to lobbying so you can rule that out:
1) change your order to 3/2013 and get the ceramic brakes
2) hope and pray that BMW makes it available sooner and check again in early December before your car goes status 112
Generally I don't recommend hope and pray strategies. They tend to fail.
