Good news on the confirms 
I ordered 02/05 - very similar to Peterdoherty's only less options and I've been bumped to BW51. Feel a call to VW CS coming on. Cant understand why my order has been delayed by 3 months. 
Didn't someone else on another thread mention their 51 was now back to a more reasonable, but still delayed, BW? Hopefully this is the case for you but looking at your spec I cant understand why mines is being built before you. VW logic strikes again I'm afraid.
I was dreading becoming a member of the BW51 club
