They were at 115k worldwide partway into the reveal. I'd say if you ordered at 10:15, you're probably in the first 10k in the US. What number were you in line at your store? Multiply that by 100 (about the # of US Tesla stores). Give or take a few thousand (depending on how fast orders were going through at your store compared to others) that is about your place in line. My store had connection issues, so even though I was #27 waiting outside, I didn't order until 10:30am, and was actually about #20 in my store to order (other line was slower).
If Musk says they hope to deliver 100,000 to 200,000 by the end of 2017, I guarantee we'd both get ours next year even if they don't come close to meeting their goals. If they do meet that target, I would probably even get my wife's next year, though like I said, I'd hold off on delivery of that until just after Jan 1 so I could get a second tax credit.
