Yes it is order only at this point, production (for RHD anyway) starts in April for both 30D and M-Sport.  My dealer is owned by BMW Australia which is in turn owned by the factory, so they have a lot more info than others normally.  I was able to lock down my order with pricing and everything now.  It will be a guilt free fun family car for us.   The biggest problem with our X5M and E63 is that the missus always complaints how unenvironmentally friendly it is and the fact that we have to refuel so often.
