Keep posting rumors, but if anyone has been on a tour or has hard data, we all want more data. We had reports of half of the cars on the line being X, but that was one report. There could have been a big batch week, testing full out X production and they may have returned to smaller X production. Plant operations are very conjectural at this point. The only hard data we have is anecdotal delivery reports and X tracker rising from 8 yesterday to 12 deliveries today.
Anecdotal reports seem to show Tesla shipping east early and then finishing California and plant deliveries later to ship the Sig's in the smallest window possible. Keeping this process top secret, even within Tesla, seems to have made this national roll-out less effective. If they do finish shipping US Sig's in the first week or two of 2016 and start shipping production models, I think this will be a big win.
