Did as you guys told me and called VW exec. They just called me back:
BUILD WEEK 35... (unconfirmed)!WOO!
Prior to this I was on unconfirmed BW 39/40.
Really really pleased with this. I asked if they knew when things would be confirmed. Was told "We are currently on BW 33, so everything up to 33 is confirmed. Therefore you can expect to be BW confirmed in a week or two." (EDIT: 33 is 7 weeks away so this matches the theory of 4 weeks before confirmation + 3 weeks for shut down.)
Awesomeness.
Gotta find some cash to pay for it now...
