To give you a background, I've postponed delivery to 2016 for tax reasons. So few minutes ago I've missed a call from Tesla (caller # in Palo Alto). Voicemail was proposing a late December delivery with 2016 VIN.
As far as I understand, in order to do so, they have to start production really soon and badge 2016 VIN on it, so probably they are already doing that for everyone.
PS: I'm hoping those of you waiting for 2016 VIN will make your order, because after 3 calls and 1 email like that I can see their effort in meeting yearly goal. They need it, please help if all you care about is VIN.
PPS: on previous calls and email new VIN wasn't mentioned, just faster delivery
