I see we are thinking along the same line here - I posted something very similar in the Social Chat thread a few hours before you. (Maybe that wasn't the right thread for this...)
Anyway, I think that even if our unofficial tally is not 100% accurate, it surely indicates Tesla is very close to that milestone. They can and - in my opinion - should use this as a PR opportunity for Model X, and naturally this will be a catalyst to TSLA as well. (Just not sure how big and how long lasting).
Assuming they get to 10k by mid January, they could do a press release during the 2nd week of the month to start the hype about the Model X production version reveal at the Detroit Motor Show. Alternativley, they could make the announcement part of the reveal in Motor City. (I think it is pretty much the consensus here at TMC, that the final revision of X will debut at the Motor Show, right?)
If they don't get to 10k by then, or for whatever reason, the production version will not be shown in Detroit, I expect the 10k announcement to be part of the Q4 2013/2014 projection materials in February.
