I am a New England 8xx Sig X res holder, and have a 5xx VIN, but absolutely no news. I am lucky to hear from my DS monthly - and only after repeated emails and voicemails. My DS recently confirmed in late December he "hasn't heard anything at all " and is "busy with Model S deliveries" so who knows. The communication vacuum is frustrating, but at this point I am hoping for end of January best case.... The reality is it's a broken process and at best a beta in terms of delivery.
