Just spoke with my DS - she also confirmed the new seat/airbag issue as the reason for delays, but based on what else she said, I'm a bit skeptical that any of our deliveries are happening for another couple of weeks, (at least).
I went into production 11/21 and am picking up in Fremont, so logically you'd think I'd have a pretty early delivery relative to most that are on the spreadsheet. BUT she said they are HOPING/TRYING to have mine done before the END OF DECEMBER. So that's a bummer, and perhaps doesn't bode well for anyone else hoping for an early Christmas present (and maybe even anyone who was planning to claim that federal rebate for 2014...).
I would guess a lot of us get are going to get pushed into January (despite the negative effects that will have on Tesla's Q4 revenue numbers).
But I'm pessimist by nature, so hopefully Tesla will come through and pleasantly surprise me - I can't wait for SOMEONE here to finally take delivery!
